Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507058, here are decompositions:

109 + 31506949 = 31507058
127 + 31506931 = 31507058
151 + 31506907 = 31507058
229 + 31506829 = 31507058
277 + 31506781 = 31507058
547 + 31506511 = 31507058
691 + 31506367 = 31507058
727 + 31506331 = 31507058

Showing the first eight; more decompositions exist.
