Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539714, here are decompositions:

7 + 31539707 = 31539714
43 + 31539671 = 31539714
53 + 31539661 = 31539714
71 + 31539643 = 31539714
127 + 31539587 = 31539714
131 + 31539583 = 31539714
191 + 31539523 = 31539714
293 + 31539421 = 31539714

Showing the first eight; more decompositions exist.
