Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045786, here are decompositions:

23 + 1045763 = 1045786
47 + 1045739 = 1045786
59 + 1045727 = 1045786
107 + 1045679 = 1045786
179 + 1045607 = 1045786
227 + 1045559 = 1045786
239 + 1045547 = 1045786
257 + 1045529 = 1045786

Showing the first eight; more decompositions exist.
