Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471472, here are decompositions:

3 + 31471469 = 31471472
61 + 31471411 = 31471472
349 + 31471123 = 31471472
379 + 31471093 = 31471472
421 + 31471051 = 31471472
619 + 31470853 = 31471472
673 + 31470799 = 31471472
691 + 31470781 = 31471472

Showing the first eight; more decompositions exist.
