Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540734, here are decompositions:

7 + 31540727 = 31540734
11 + 31540723 = 31540734
41 + 31540693 = 31540734
83 + 31540651 = 31540734
97 + 31540637 = 31540734
103 + 31540631 = 31540734
233 + 31540501 = 31540734
241 + 31540493 = 31540734

Showing the first eight; more decompositions exist.
