Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496472, here are decompositions:

23 + 31496449 = 31496472
31 + 31496441 = 31496472
43 + 31496429 = 31496472
53 + 31496419 = 31496472
83 + 31496389 = 31496472
101 + 31496371 = 31496472
103 + 31496369 = 31496472
151 + 31496321 = 31496472

Showing the first eight; more decompositions exist.
