Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981502, here are decompositions:

29 + 981473 = 981502
59 + 981443 = 981502
83 + 981419 = 981502
191 + 981311 = 981502
239 + 981263 = 981502
281 + 981221 = 981502
293 + 981209 = 981502
479 + 981023 = 981502

Showing the first eight; more decompositions exist.
