Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540776, here are decompositions:

53 + 31540723 = 31540776
67 + 31540709 = 31540776
83 + 31540693 = 31540776
97 + 31540679 = 31540776
107 + 31540669 = 31540776
139 + 31540637 = 31540776
277 + 31540499 = 31540776
283 + 31540493 = 31540776

Showing the first eight; more decompositions exist.
