Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981544, here are decompositions:

17 + 981527 = 981544
71 + 981473 = 981544
101 + 981443 = 981544
107 + 981437 = 981544
167 + 981377 = 981544
233 + 981311 = 981544
257 + 981287 = 981544
281 + 981263 = 981544

Showing the first eight; more decompositions exist.
