Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2146, here are decompositions:
- 3 + 2143 = 2146
- 5 + 2141 = 2146
- 17 + 2129 = 2146
- 47 + 2099 = 2146
- 59 + 2087 = 2146
- 83 + 2063 = 2146
- 107 + 2039 = 2146
- 149 + 1997 = 2146
Showing the first eight; more decompositions exist.

The digit sequence 2146 first appears in π at position 650 of the decimal expansion (the 650ordinal-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.
