Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539496, here are decompositions:

29 + 31539467 = 31539496
83 + 31539413 = 31539496
167 + 31539329 = 31539496
353 + 31539143 = 31539496
449 + 31539047 = 31539496
509 + 31538987 = 31539496
743 + 31538753 = 31539496
1019 + 31538477 = 31539496

Showing the first eight; more decompositions exist.
