Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539176, here are decompositions:

13 + 31539163 = 31539176
103 + 31539073 = 31539176
349 + 31538827 = 31539176
397 + 31538779 = 31539176
433 + 31538743 = 31539176
457 + 31538719 = 31539176
463 + 31538713 = 31539176
523 + 31538653 = 31539176

Showing the first eight; more decompositions exist.
