Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464970, here are decompositions:

3 + 31464967 = 31464970
23 + 31464947 = 31464970
29 + 31464941 = 31464970
149 + 31464821 = 31464970
239 + 31464731 = 31464970
269 + 31464701 = 31464970
353 + 31464617 = 31464970
389 + 31464581 = 31464970

Showing the first eight; more decompositions exist.
