Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148664, here are decompositions:
- 31 + 148633 = 148664
- 37 + 148627 = 148664
- 127 + 148537 = 148664
- 151 + 148513 = 148664
- 163 + 148501 = 148664
- 181 + 148483 = 148664
- 193 + 148471 = 148664
- 277 + 148387 = 148664
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 148,664 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 148664 first appears in π at position 381,773 of the decimal expansion (the 381,773ordinal-suffix:rd 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.
