Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540696, here are decompositions:

3 + 31540693 = 31540696
17 + 31540679 = 31540696
53 + 31540643 = 31540696
59 + 31540637 = 31540696
167 + 31540529 = 31540696
197 + 31540499 = 31540696
353 + 31540343 = 31540696
479 + 31540217 = 31540696

Showing the first eight; more decompositions exist.
