Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470848, here are decompositions:

61 + 31470787 = 31470848
67 + 31470781 = 31470848
127 + 31470721 = 31470848
139 + 31470709 = 31470848
229 + 31470619 = 31470848
379 + 31470469 = 31470848
439 + 31470409 = 31470848
631 + 31470217 = 31470848

Showing the first eight; more decompositions exist.
