Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977664, here are decompositions:
- 53 + 977611 = 977664
- 71 + 977593 = 977664
- 73 + 977591 = 977664
- 97 + 977567 = 977664
- 151 + 977513 = 977664
- 157 + 977507 = 977664
- 227 + 977437 = 977664
- 251 + 977413 = 977664
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 977,664 and was likely granted around 1910.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 977664 first appears in π at position 177,966 of the decimal expansion (the 177,966ordinal-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.
