Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627102, here are decompositions:

11 + 31627091 = 31627102
29 + 31627073 = 31627102
233 + 31626869 = 31627102
263 + 31626839 = 31627102
569 + 31626533 = 31627102
641 + 31626461 = 31627102
719 + 31626383 = 31627102
743 + 31626359 = 31627102

Showing the first eight; more decompositions exist.
