Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20016, here are decompositions:
- 5 + 20011 = 20016
- 19 + 19997 = 20016
- 23 + 19993 = 20016
- 37 + 19979 = 20016
- 43 + 19973 = 20016
- 53 + 19963 = 20016
- 67 + 19949 = 20016
- 79 + 19937 = 20016
Showing the first eight; more decompositions exist.

The digit sequence 20016 first appears in π at position 23,484 of the decimal expansion (the 23,484ordinal-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.
