Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470082, here are decompositions:

179 + 31469903 = 31470082
233 + 31469849 = 31470082
269 + 31469813 = 31470082
359 + 31469723 = 31470082
461 + 31469621 = 31470082
503 + 31469579 = 31470082
521 + 31469561 = 31470082
563 + 31469519 = 31470082

Showing the first eight; more decompositions exist.
