Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469116, here are decompositions:

47 + 31469069 = 31469116
83 + 31469033 = 31469116
89 + 31469027 = 31469116
149 + 31468967 = 31469116
197 + 31468919 = 31469116
293 + 31468823 = 31469116
359 + 31468757 = 31469116
389 + 31468727 = 31469116

Showing the first eight; more decompositions exist.
