Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470664, here are decompositions:

3 + 31470661 = 31470664
11 + 31470653 = 31470664
23 + 31470641 = 31470664
41 + 31470623 = 31470664
83 + 31470581 = 31470664
101 + 31470563 = 31470664
107 + 31470557 = 31470664
311 + 31470353 = 31470664

Showing the first eight; more decompositions exist.
