Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627412, here are decompositions:

79 + 31627333 = 31627412
109 + 31627303 = 31627412
151 + 31627261 = 31627412
163 + 31627249 = 31627412
211 + 31627201 = 31627412
379 + 31627033 = 31627412
433 + 31626979 = 31627412
571 + 31626841 = 31627412

Showing the first eight; more decompositions exist.
