Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981514, here are decompositions:

41 + 981473 = 981514
47 + 981467 = 981514
71 + 981443 = 981514
137 + 981377 = 981514
227 + 981287 = 981514
251 + 981263 = 981514
293 + 981221 = 981514
491 + 981023 = 981514

Showing the first eight; more decompositions exist.
