Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494010, here are decompositions:

11 + 31493999 = 31494010
59 + 31493951 = 31494010
83 + 31493927 = 31494010
101 + 31493909 = 31494010
227 + 31493783 = 31494010
293 + 31493717 = 31494010
491 + 31493519 = 31494010
563 + 31493447 = 31494010

Showing the first eight; more decompositions exist.
