Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466806, here are decompositions:

47 + 31466759 = 31466806
53 + 31466753 = 31466806
113 + 31466693 = 31466806
149 + 31466657 = 31466806
179 + 31466627 = 31466806
257 + 31466549 = 31466806
419 + 31466387 = 31466806
479 + 31466327 = 31466806

Showing the first eight; more decompositions exist.
