Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516934, here are decompositions:

157 + 31516777 = 31516934
181 + 31516753 = 31516934
307 + 31516627 = 31516934
331 + 31516603 = 31516934
367 + 31516567 = 31516934
433 + 31516501 = 31516934
523 + 31516411 = 31516934
577 + 31516357 = 31516934

Showing the first eight; more decompositions exist.
