Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627702, here are decompositions:

53 + 31627649 = 31627702
101 + 31627601 = 31627702
191 + 31627511 = 31627702
311 + 31627391 = 31627702
383 + 31627319 = 31627702
569 + 31627133 = 31627702
809 + 31626893 = 31627702
863 + 31626839 = 31627702

Showing the first eight; more decompositions exist.
