Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 147664, here are decompositions:
- 3 + 147661 = 147664
- 17 + 147647 = 147664
- 47 + 147617 = 147664
- 107 + 147557 = 147664
- 113 + 147551 = 147664
- 263 + 147401 = 147664
- 311 + 147353 = 147664
- 317 + 147347 = 147664
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 147,664 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 147664 first appears in π at position 888,992 of the decimal expansion (the 888,992ordinal-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.
