Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537448, here are decompositions:

109 + 31537339 = 31537448
139 + 31537309 = 31537448
181 + 31537267 = 31537448
409 + 31537039 = 31537448
421 + 31537027 = 31537448
457 + 31536991 = 31537448
577 + 31536871 = 31537448
601 + 31536847 = 31537448

Showing the first eight; more decompositions exist.
