Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507046, here are decompositions:

37 + 31507009 = 31507046
73 + 31506973 = 31507046
97 + 31506949 = 31507046
139 + 31506907 = 31507046
223 + 31506823 = 31507046
349 + 31506697 = 31507046
523 + 31506523 = 31507046
673 + 31506373 = 31507046

Showing the first eight; more decompositions exist.
