Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466848, here are decompositions:

89 + 31466759 = 31466848
191 + 31466657 = 31466848
251 + 31466597 = 31466848
461 + 31466387 = 31466848
467 + 31466381 = 31466848
521 + 31466327 = 31466848
557 + 31466291 = 31466848
599 + 31466249 = 31466848

Showing the first eight; more decompositions exist.
