Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470562, here are decompositions:

5 + 31470557 = 31470562
239 + 31470323 = 31470562
269 + 31470293 = 31470562
353 + 31470209 = 31470562
419 + 31470143 = 31470562
659 + 31469903 = 31470562
701 + 31469861 = 31470562
821 + 31469741 = 31470562

Showing the first eight; more decompositions exist.
