Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153664, here are decompositions:
- 23 + 153641 = 153664
- 41 + 153623 = 153664
- 53 + 153611 = 153664
- 101 + 153563 = 153664
- 107 + 153557 = 153664
- 131 + 153533 = 153664
- 227 + 153437 = 153664
- 257 + 153407 = 153664
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 153,664 and was likely granted around 1873.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 153664 first appears in π at position 570,764 of the decimal expansion (the 570,764ordinal-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.
