Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045810, here are decompositions:

11 + 1045799 = 1045810
47 + 1045763 = 1045810
71 + 1045739 = 1045810
83 + 1045727 = 1045810
131 + 1045679 = 1045810
167 + 1045643 = 1045810
239 + 1045571 = 1045810
251 + 1045559 = 1045810

Showing the first eight; more decompositions exist.
