Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507096, here are decompositions:

59 + 31507037 = 31507096
167 + 31506929 = 31507096
347 + 31506749 = 31507096
353 + 31506743 = 31507096
419 + 31506677 = 31507096
617 + 31506479 = 31507096
653 + 31506443 = 31507096
659 + 31506437 = 31507096

Showing the first eight; more decompositions exist.
