Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157964, here are decompositions:
- 13 + 157951 = 157964
- 31 + 157933 = 157964
- 67 + 157897 = 157964
- 97 + 157867 = 157964
- 127 + 157837 = 157964
- 151 + 157813 = 157964
- 193 + 157771 = 157964
- 337 + 157627 = 157964
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 157,964 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 157964 first appears in π at position 706,391 of the decimal expansion (the 706,391ordinal-suffix:st 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.
