Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540674, here are decompositions:

5 + 31540669 = 31540674
17 + 31540657 = 31540674
23 + 31540651 = 31540674
31 + 31540643 = 31540674
37 + 31540637 = 31540674
43 + 31540631 = 31540674
101 + 31540573 = 31540674
173 + 31540501 = 31540674

Showing the first eight; more decompositions exist.
