Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 90646, here are decompositions:

5 + 90641 = 90646
29 + 90617 = 90646
47 + 90599 = 90646
113 + 90533 = 90646
173 + 90473 = 90646
239 + 90407 = 90646
293 + 90353 = 90646
383 + 90263 = 90646

Showing the first eight; more decompositions exist.
