Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468108, here are decompositions:

11 + 31468097 = 31468108
41 + 31468067 = 31468108
107 + 31468001 = 31468108
197 + 31467911 = 31468108
389 + 31467719 = 31468108
431 + 31467677 = 31468108
461 + 31467647 = 31468108
521 + 31467587 = 31468108

Showing the first eight; more decompositions exist.
