Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494692, here are decompositions:

3 + 31494689 = 31494692
13 + 31494679 = 31494692
109 + 31494583 = 31494692
139 + 31494553 = 31494692
223 + 31494469 = 31494692
601 + 31494091 = 31494692
613 + 31494079 = 31494692
709 + 31493983 = 31494692

Showing the first eight; more decompositions exist.
