Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003898, here are decompositions:

19 + 1003879 = 1003898
79 + 1003819 = 1003898
127 + 1003771 = 1003898
151 + 1003747 = 1003898
157 + 1003741 = 1003898
271 + 1003627 = 1003898
277 + 1003621 = 1003898
349 + 1003549 = 1003898

Showing the first eight; more decompositions exist.
