Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466194, here are decompositions:

131 + 31466063 = 31466194
191 + 31466003 = 31466194
467 + 31465727 = 31466194
521 + 31465673 = 31466194
563 + 31465631 = 31466194
593 + 31465601 = 31466194
647 + 31465547 = 31466194
743 + 31465451 = 31466194

Showing the first eight; more decompositions exist.
