Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539022, here are decompositions:

71 + 31538951 = 31539022
233 + 31538789 = 31539022
269 + 31538753 = 31539022
293 + 31538729 = 31539022
311 + 31538711 = 31539022
443 + 31538579 = 31539022
461 + 31538561 = 31539022
761 + 31538261 = 31539022

Showing the first eight; more decompositions exist.
