Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476618, here are decompositions:

7 + 31476611 = 31476618
11 + 31476607 = 31476618
31 + 31476587 = 31476618
67 + 31476551 = 31476618
71 + 31476547 = 31476618
101 + 31476517 = 31476618
109 + 31476509 = 31476618
157 + 31476461 = 31476618

Showing the first eight; more decompositions exist.
