Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470898, here are decompositions:

29 + 31470869 = 31470898
71 + 31470827 = 31470898
197 + 31470701 = 31470898
257 + 31470641 = 31470898
269 + 31470629 = 31470898
317 + 31470581 = 31470898
677 + 31470221 = 31470898
911 + 31469987 = 31470898

Showing the first eight; more decompositions exist.
