Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501076, here are decompositions:

37 + 31501039 = 31501076
67 + 31501009 = 31501076
97 + 31500979 = 31501076
109 + 31500967 = 31501076
157 + 31500919 = 31501076
223 + 31500853 = 31501076
283 + 31500793 = 31501076
487 + 31500589 = 31501076

Showing the first eight; more decompositions exist.
