Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455676, here are decompositions:

29 + 31455647 = 31455676
53 + 31455623 = 31455676
173 + 31455503 = 31455676
227 + 31455449 = 31455676
257 + 31455419 = 31455676
383 + 31455293 = 31455676
467 + 31455209 = 31455676
479 + 31455197 = 31455676

Showing the first eight; more decompositions exist.
