Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164418, here are decompositions:
- 5 + 164413 = 164418
- 31 + 164387 = 164418
- 41 + 164377 = 164418
- 47 + 164371 = 164418
- 61 + 164357 = 164418
- 97 + 164321 = 164418
- 109 + 164309 = 164418
- 127 + 164291 = 164418
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 164,418 and was likely granted around 1874.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 164418 first appears in π at position 255,633 of the decimal expansion (the 255,633ordinal-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.
