Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627976, here are decompositions:

7 + 31627969 = 31627976
73 + 31627903 = 31627976
97 + 31627879 = 31627976
223 + 31627753 = 31627976
337 + 31627639 = 31627976
349 + 31627627 = 31627976
409 + 31627567 = 31627976
433 + 31627543 = 31627976

Showing the first eight; more decompositions exist.
