Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31469146, here are decompositions:

3 + 31469143 = 31469146
113 + 31469033 = 31469146
179 + 31468967 = 31469146
227 + 31468919 = 31469146
353 + 31468793 = 31469146
389 + 31468757 = 31469146
419 + 31468727 = 31469146
479 + 31468667 = 31469146

Showing the first eight; more decompositions exist.
