Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539706, here are decompositions:

47 + 31539659 = 31539706
113 + 31539593 = 31539706
137 + 31539569 = 31539706
239 + 31539467 = 31539706
293 + 31539413 = 31539706
353 + 31539353 = 31539706
563 + 31539143 = 31539706
617 + 31539089 = 31539706

Showing the first eight; more decompositions exist.
