Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151164, here are decompositions:
- 7 + 151157 = 151164
- 11 + 151153 = 151164
- 23 + 151141 = 151164
- 43 + 151121 = 151164
- 73 + 151091 = 151164
- 107 + 151057 = 151164
- 113 + 151051 = 151164
- 137 + 151027 = 151164
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 151,164 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 151164 first appears in π at position 595,126 of the decimal expansion (the 595,126ordinal-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.
