Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045898, here are decompositions:

79 + 1045819 = 1045898
97 + 1045801 = 1045898
277 + 1045621 = 1045898
349 + 1045549 = 1045898
487 + 1045411 = 1045898
577 + 1045321 = 1045898
661 + 1045237 = 1045898
769 + 1045129 = 1045898

Showing the first eight; more decompositions exist.
