Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470838, here are decompositions:

5 + 31470833 = 31470838
11 + 31470827 = 31470838
137 + 31470701 = 31470838
197 + 31470641 = 31470838
257 + 31470581 = 31470838
281 + 31470557 = 31470838
479 + 31470359 = 31470838
617 + 31470221 = 31470838

Showing the first eight; more decompositions exist.
