Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455496, here are decompositions:

47 + 31455449 = 31455496
197 + 31455299 = 31455496
227 + 31455269 = 31455496
257 + 31455239 = 31455496
587 + 31454909 = 31455496
593 + 31454903 = 31455496
659 + 31454837 = 31455496
827 + 31454669 = 31455496

Showing the first eight; more decompositions exist.
