Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466770, here are decompositions:

11 + 31466759 = 31466770
17 + 31466753 = 31466770
113 + 31466657 = 31466770
173 + 31466597 = 31466770
383 + 31466387 = 31466770
389 + 31466381 = 31466770
443 + 31466327 = 31466770
479 + 31466291 = 31466770

Showing the first eight; more decompositions exist.
