Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455796, here are decompositions:

83 + 31455713 = 31455796
149 + 31455647 = 31455796
173 + 31455623 = 31455796
263 + 31455533 = 31455796
293 + 31455503 = 31455796
347 + 31455449 = 31455796
503 + 31455293 = 31455796
557 + 31455239 = 31455796

Showing the first eight; more decompositions exist.
