Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539562, here are decompositions:

149 + 31539413 = 31539562
233 + 31539329 = 31539562
419 + 31539143 = 31539562
479 + 31539083 = 31539562
773 + 31538789 = 31539562
809 + 31538753 = 31539562
983 + 31538579 = 31539562
1151 + 31538411 = 31539562

Showing the first eight; more decompositions exist.
