Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539466, here are decompositions:

53 + 31539413 = 31539466
89 + 31539377 = 31539466
113 + 31539353 = 31539466
137 + 31539329 = 31539466
383 + 31539083 = 31539466
419 + 31539047 = 31539466
479 + 31538987 = 31539466
659 + 31538807 = 31539466

Showing the first eight; more decompositions exist.
