Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627886, here are decompositions:

7 + 31627879 = 31627886
313 + 31627573 = 31627886
349 + 31627537 = 31627886
643 + 31627243 = 31627886
853 + 31627033 = 31627886
859 + 31627027 = 31627886
907 + 31626979 = 31627886
919 + 31626967 = 31627886

Showing the first eight; more decompositions exist.
