Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539736, here are decompositions:

23 + 31539713 = 31539736
29 + 31539707 = 31539736
149 + 31539587 = 31539736
167 + 31539569 = 31539736
269 + 31539467 = 31539736
359 + 31539377 = 31539736
383 + 31539353 = 31539736
593 + 31539143 = 31539736

Showing the first eight; more decompositions exist.
