Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540668, here are decompositions:

11 + 31540657 = 31540668
17 + 31540651 = 31540668
31 + 31540637 = 31540668
37 + 31540631 = 31540668
139 + 31540529 = 31540668
167 + 31540501 = 31540668
179 + 31540489 = 31540668
197 + 31540471 = 31540668

Showing the first eight; more decompositions exist.
