Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543336, here are decompositions:

5 + 31543331 = 31543336
113 + 31543223 = 31543336
173 + 31543163 = 31543336
233 + 31543103 = 31543336
257 + 31543079 = 31543336
269 + 31543067 = 31543336
317 + 31543019 = 31543336
479 + 31542857 = 31543336

Showing the first eight; more decompositions exist.
