Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19586, here are decompositions:
- 3 + 19583 = 19586
- 43 + 19543 = 19586
- 79 + 19507 = 19586
- 97 + 19489 = 19586
- 103 + 19483 = 19586
- 109 + 19477 = 19586
- 139 + 19447 = 19586
- 157 + 19429 = 19586
Showing the first eight; more decompositions exist.

The digit sequence 19586 first appears in π at position 190,946 of the decimal expansion (the 190,946ordinal-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.
