Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015898, here are decompositions:

7 + 1015891 = 1015898
151 + 1015747 = 1015898
271 + 1015627 = 1015898
337 + 1015561 = 1015898
349 + 1015549 = 1015898
397 + 1015501 = 1015898
439 + 1015459 = 1015898
691 + 1015207 = 1015898

Showing the first eight; more decompositions exist.
