Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540682, here are decompositions:

3 + 31540679 = 31540682
13 + 31540669 = 31540682
31 + 31540651 = 31540682
109 + 31540573 = 31540682
181 + 31540501 = 31540682
193 + 31540489 = 31540682
211 + 31540471 = 31540682
241 + 31540441 = 31540682

Showing the first eight; more decompositions exist.
