Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540336, here are decompositions:

173 + 31540163 = 31540336
227 + 31540109 = 31540336
479 + 31539857 = 31540336
599 + 31539737 = 31540336
677 + 31539659 = 31540336
743 + 31539593 = 31540336
983 + 31539353 = 31540336
1193 + 31539143 = 31540336

Showing the first eight; more decompositions exist.
