Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19468, here are decompositions:
- 5 + 19463 = 19468
- 11 + 19457 = 19468
- 41 + 19427 = 19468
- 47 + 19421 = 19468
- 89 + 19379 = 19468
- 149 + 19319 = 19468
- 167 + 19301 = 19468
- 179 + 19289 = 19468
Showing the first eight; more decompositions exist.

The digit sequence 19468 first appears in π at position 146,138 of the decimal expansion (the 146,138ordinal-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.
