Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8741664, here are decompositions:
- 23 + 8741641 = 8741664
- 101 + 8741563 = 8741664
- 131 + 8741533 = 8741664
- 193 + 8741471 = 8741664
- 227 + 8741437 = 8741664
- 233 + 8741431 = 8741664
- 263 + 8741401 = 8741664
- 271 + 8741393 = 8741664
Showing the first eight; more decompositions exist.

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 8,741,664 and was likely granted around 2014.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 8741664 first appears in π at position 865,444 of the decimal expansion (the 865,444ordinal-suffix:th digit after the integer 3).
Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
