Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476624, here are decompositions:

13 + 31476611 = 31476624
17 + 31476607 = 31476624
31 + 31476593 = 31476624
37 + 31476587 = 31476624
73 + 31476551 = 31476624
107 + 31476517 = 31476624
163 + 31476461 = 31476624
167 + 31476457 = 31476624

Showing the first eight; more decompositions exist.
