Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567078, here are decompositions:

29 + 31567049 = 31567078
167 + 31566911 = 31567078
239 + 31566839 = 31567078
251 + 31566827 = 31567078
281 + 31566797 = 31567078
419 + 31566659 = 31567078
467 + 31566611 = 31567078
479 + 31566599 = 31567078

Showing the first eight; more decompositions exist.
