Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627370, here are decompositions:

13 + 31627357 = 31627370
37 + 31627333 = 31627370
67 + 31627303 = 31627370
109 + 31627261 = 31627370
127 + 31627243 = 31627370
337 + 31627033 = 31627370
487 + 31626883 = 31627370
661 + 31626709 = 31627370

Showing the first eight; more decompositions exist.
