Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539716, here are decompositions:

3 + 31539713 = 31539716
67 + 31539649 = 31539716
73 + 31539643 = 31539716
193 + 31539523 = 31539716
277 + 31539439 = 31539716
349 + 31539367 = 31539716
367 + 31539349 = 31539716
379 + 31539337 = 31539716

Showing the first eight; more decompositions exist.
