Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470768, here are decompositions:

47 + 31470721 = 31470768
59 + 31470709 = 31470768
67 + 31470701 = 31470768
107 + 31470661 = 31470768
127 + 31470641 = 31470768
139 + 31470629 = 31470768
149 + 31470619 = 31470768
211 + 31470557 = 31470768

Showing the first eight; more decompositions exist.
