Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574610, here are decompositions:

47 + 31574563 = 31574610
79 + 31574531 = 31574610
103 + 31574507 = 31574610
113 + 31574497 = 31574610
131 + 31574479 = 31574610
157 + 31574453 = 31574610
167 + 31574443 = 31574610
173 + 31574437 = 31574610

Showing the first eight; more decompositions exist.
