Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627196, here are decompositions:

127 + 31627069 = 31627196
163 + 31627033 = 31627196
229 + 31626967 = 31627196
313 + 31626883 = 31627196
409 + 31626787 = 31627196
487 + 31626709 = 31627196
577 + 31626619 = 31627196
607 + 31626589 = 31627196

Showing the first eight; more decompositions exist.
