Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483646, here are decompositions:

97 + 31483549 = 31483646
193 + 31483453 = 31483646
199 + 31483447 = 31483646
277 + 31483369 = 31483646
409 + 31483237 = 31483646
433 + 31483213 = 31483646
577 + 31483069 = 31483646
643 + 31483003 = 31483646

Showing the first eight; more decompositions exist.
