Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539412, here are decompositions:

11 + 31539401 = 31539412
59 + 31539353 = 31539412
83 + 31539329 = 31539412
269 + 31539143 = 31539412
461 + 31538951 = 31539412
659 + 31538753 = 31539412
683 + 31538729 = 31539412
701 + 31538711 = 31539412

Showing the first eight; more decompositions exist.
