Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470466, here are decompositions:

23 + 31470443 = 31470466
107 + 31470359 = 31470466
113 + 31470353 = 31470466
173 + 31470293 = 31470466
257 + 31470209 = 31470466
479 + 31469987 = 31470466
563 + 31469903 = 31470466
617 + 31469849 = 31470466

Showing the first eight; more decompositions exist.
