Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20012, here are decompositions:
- 19 + 19993 = 20012
- 151 + 19861 = 20012
- 193 + 19819 = 20012
- 199 + 19813 = 20012
- 211 + 19801 = 20012
- 313 + 19699 = 20012
- 331 + 19681 = 20012
- 409 + 19603 = 20012
Showing the first eight; more decompositions exist.

The digit sequence 20012 first appears in π at position 109,340 of the decimal expansion (the 109,340ordinal-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.
