Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507076, here are decompositions:

67 + 31507009 = 31507076
103 + 31506973 = 31507076
127 + 31506949 = 31507076
277 + 31506799 = 31507076
283 + 31506793 = 31507076
379 + 31506697 = 31507076
499 + 31506577 = 31507076
547 + 31506529 = 31507076

Showing the first eight; more decompositions exist.
