Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31444976, here are decompositions:

37 + 31444939 = 31444976
97 + 31444879 = 31444976
139 + 31444837 = 31444976
163 + 31444813 = 31444976
349 + 31444627 = 31444976
439 + 31444537 = 31444976
487 + 31444489 = 31444976
499 + 31444477 = 31444976

Showing the first eight; more decompositions exist.
