Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449510, here are decompositions:

11 + 31449499 = 31449510
17 + 31449493 = 31449510
31 + 31449479 = 31449510
47 + 31449463 = 31449510
61 + 31449449 = 31449510
89 + 31449421 = 31449510
101 + 31449409 = 31449510
107 + 31449403 = 31449510

Showing the first eight; more decompositions exist.
