Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537804, here are decompositions:

83 + 31537721 = 31537804
113 + 31537691 = 31537804
173 + 31537631 = 31537804
257 + 31537547 = 31537804
491 + 31537313 = 31537804
653 + 31537151 = 31537804
677 + 31537127 = 31537804
761 + 31537043 = 31537804

Showing the first eight; more decompositions exist.
