Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539826, here are decompositions:

5 + 31539821 = 31539826
89 + 31539737 = 31539826
113 + 31539713 = 31539826
167 + 31539659 = 31539826
233 + 31539593 = 31539826
239 + 31539587 = 31539826
257 + 31539569 = 31539826
359 + 31539467 = 31539826

Showing the first eight; more decompositions exist.
