Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539710, here are decompositions:

3 + 31539707 = 31539710
61 + 31539649 = 31539710
67 + 31539643 = 31539710
127 + 31539583 = 31539710
211 + 31539499 = 31539710
271 + 31539439 = 31539710
373 + 31539337 = 31539710
379 + 31539331 = 31539710

Showing the first eight; more decompositions exist.
