Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543054, here are decompositions:

83 + 31542971 = 31543054
113 + 31542941 = 31543054
173 + 31542881 = 31543054
197 + 31542857 = 31543054
227 + 31542827 = 31543054
467 + 31542587 = 31543054
617 + 31542437 = 31543054
677 + 31542377 = 31543054

Showing the first eight; more decompositions exist.
