Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31578796, here are decompositions:

5 + 31578791 = 31578796
59 + 31578737 = 31578796
173 + 31578623 = 31578796
239 + 31578557 = 31578796
257 + 31578539 = 31578796
467 + 31578329 = 31578796
479 + 31578317 = 31578796
503 + 31578293 = 31578796

Showing the first eight; more decompositions exist.
