Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449516, here are decompositions:

17 + 31449499 = 31449516
23 + 31449493 = 31449516
37 + 31449479 = 31449516
53 + 31449463 = 31449516
67 + 31449449 = 31449516
107 + 31449409 = 31449516
113 + 31449403 = 31449516
139 + 31449377 = 31449516

Showing the first eight; more decompositions exist.
