Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627906, here are decompositions:

3 + 31627903 = 31627906
17 + 31627889 = 31627906
113 + 31627793 = 31627906
179 + 31627727 = 31627906
257 + 31627649 = 31627906
347 + 31627559 = 31627906
587 + 31627319 = 31627906
617 + 31627289 = 31627906

Showing the first eight; more decompositions exist.
