Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507034, here are decompositions:

61 + 31506973 = 31507034
103 + 31506931 = 31507034
127 + 31506907 = 31507034
193 + 31506841 = 31507034
211 + 31506823 = 31507034
241 + 31506793 = 31507034
337 + 31506697 = 31507034
457 + 31506577 = 31507034

Showing the first eight; more decompositions exist.
