Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539316, here are decompositions:

173 + 31539143 = 31539316
227 + 31539089 = 31539316
233 + 31539083 = 31539316
269 + 31539047 = 31539316
509 + 31538807 = 31539316
563 + 31538753 = 31539316
587 + 31538729 = 31539316
827 + 31538489 = 31539316

Showing the first eight; more decompositions exist.
