Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537112, here are decompositions:

73 + 31537039 = 31537112
109 + 31537003 = 31537112
241 + 31536871 = 31537112
283 + 31536829 = 31537112
379 + 31536733 = 31537112
499 + 31536613 = 31537112
613 + 31536499 = 31537112
631 + 31536481 = 31537112

Showing the first eight; more decompositions exist.
