Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156664, here are decompositions:
- 5 + 156659 = 156664
- 23 + 156641 = 156664
- 41 + 156623 = 156664
- 71 + 156593 = 156664
- 173 + 156491 = 156664
- 197 + 156467 = 156664
- 227 + 156437 = 156664
- 293 + 156371 = 156664
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 156,664 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 156664 first appears in π at position 241,922 of the decimal expansion (the 241,922ordinal-suffix:nd 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.
