Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574936, here are decompositions:

73 + 31574863 = 31574936
157 + 31574779 = 31574936
163 + 31574773 = 31574936
373 + 31574563 = 31574936
439 + 31574497 = 31574936
457 + 31574479 = 31574936
487 + 31574449 = 31574936
499 + 31574437 = 31574936

Showing the first eight; more decompositions exist.
