Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466494, here are decompositions:

107 + 31466387 = 31466494
113 + 31466381 = 31466494
167 + 31466327 = 31466494
431 + 31466063 = 31466494
443 + 31466051 = 31466494
491 + 31466003 = 31466494
797 + 31465697 = 31466494
821 + 31465673 = 31466494

Showing the first eight; more decompositions exist.
