Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042898, here are decompositions:

37 + 1042861 = 1042898
61 + 1042837 = 1042898
79 + 1042819 = 1042898
139 + 1042759 = 1042898
211 + 1042687 = 1042898
379 + 1042519 = 1042898
499 + 1042399 = 1042898
541 + 1042357 = 1042898

Showing the first eight; more decompositions exist.
