Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627688, here are decompositions:

61 + 31627627 = 31627688
151 + 31627537 = 31627688
277 + 31627411 = 31627688
331 + 31627357 = 31627688
439 + 31627249 = 31627688
487 + 31627201 = 31627688
619 + 31627069 = 31627688
661 + 31627027 = 31627688

Showing the first eight; more decompositions exist.
