Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1012898, here are decompositions:

37 + 1012861 = 1012898
67 + 1012831 = 1012898
109 + 1012789 = 1012898
127 + 1012771 = 1012898
181 + 1012717 = 1012898
199 + 1012699 = 1012898
241 + 1012657 = 1012898
307 + 1012591 = 1012898

Showing the first eight; more decompositions exist.
