Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164378, here are decompositions:
- 7 + 164371 = 164378
- 37 + 164341 = 164378
- 79 + 164299 = 164378
- 127 + 164251 = 164378
- 139 + 164239 = 164378
- 229 + 164149 = 164378
- 307 + 164071 = 164378
- 367 + 164011 = 164378
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 164,378 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 164378 first appears in π at position 5,754 of the decimal expansion (the 5,754ordinal-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.
