Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144164, here are decompositions:
- 3 + 144161 = 144164
- 61 + 144103 = 144164
- 103 + 144061 = 144164
- 127 + 144037 = 144164
- 151 + 144013 = 144164
- 193 + 143971 = 144164
- 211 + 143953 = 144164
- 283 + 143881 = 144164
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 144,164 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 144164 first appears in π at position 237,624 of the decimal expansion (the 237,624ordinal-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.
