Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540662, here are decompositions:

5 + 31540657 = 31540662
11 + 31540651 = 31540662
19 + 31540643 = 31540662
31 + 31540631 = 31540662
89 + 31540573 = 31540662
163 + 31540499 = 31540662
173 + 31540489 = 31540662
191 + 31540471 = 31540662

Showing the first eight; more decompositions exist.
