Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539262, here are decompositions:

71 + 31539191 = 31539262
173 + 31539089 = 31539262
179 + 31539083 = 31539262
311 + 31538951 = 31539262
509 + 31538753 = 31539262
569 + 31538693 = 31539262
683 + 31538579 = 31539262
701 + 31538561 = 31539262

Showing the first eight; more decompositions exist.
