Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470108, here are decompositions:

11 + 31470097 = 31470108
41 + 31470067 = 31470108
71 + 31470037 = 31470108
251 + 31469857 = 31470108
311 + 31469797 = 31470108
347 + 31469761 = 31470108
367 + 31469741 = 31470108
419 + 31469689 = 31470108

Showing the first eight; more decompositions exist.
