Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981436, here are decompositions:

17 + 981419 = 981436
59 + 981377 = 981436
149 + 981287 = 981436
173 + 981263 = 981436
227 + 981209 = 981436
263 + 981173 = 981436
359 + 981077 = 981436
419 + 981017 = 981436

Showing the first eight; more decompositions exist.
