Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483692, here are decompositions:

29 + 31483663 = 31483692
43 + 31483649 = 31483692
109 + 31483583 = 31483692
139 + 31483553 = 31483692
199 + 31483493 = 31483692
223 + 31483469 = 31483692
239 + 31483453 = 31483692
263 + 31483429 = 31483692

Showing the first eight; more decompositions exist.
