Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045688, here are decompositions:

37 + 1045651 = 1045688
67 + 1045621 = 1045688
139 + 1045549 = 1045688
181 + 1045507 = 1045688
277 + 1045411 = 1045688
367 + 1045321 = 1045688
379 + 1045309 = 1045688
571 + 1045117 = 1045688

Showing the first eight; more decompositions exist.
