Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539106, here are decompositions:

17 + 31539089 = 31539106
23 + 31539083 = 31539106
59 + 31539047 = 31539106
317 + 31538789 = 31539106
353 + 31538753 = 31539106
617 + 31538489 = 31539106
773 + 31538333 = 31539106
953 + 31538153 = 31539106

Showing the first eight; more decompositions exist.
