Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543084, here are decompositions:

5 + 31543079 = 31543084
17 + 31543067 = 31543084
113 + 31542971 = 31543084
173 + 31542911 = 31543084
227 + 31542857 = 31543084
257 + 31542827 = 31543084
317 + 31542767 = 31543084
647 + 31542437 = 31543084

Showing the first eight; more decompositions exist.
