Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470394, here are decompositions:

41 + 31470353 = 31470394
71 + 31470323 = 31470394
101 + 31470293 = 31470394
173 + 31470221 = 31470394
227 + 31470167 = 31470394
251 + 31470143 = 31470394
491 + 31469903 = 31470394
653 + 31469741 = 31470394

Showing the first eight; more decompositions exist.
