Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537096, here are decompositions:

47 + 31537049 = 31537096
53 + 31537043 = 31537096
113 + 31536983 = 31537096
137 + 31536959 = 31537096
179 + 31536917 = 31537096
233 + 31536863 = 31537096
389 + 31536707 = 31537096
467 + 31536629 = 31537096

Showing the first eight; more decompositions exist.
