Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981748, here are decompositions:

17 + 981731 = 981748
41 + 981707 = 981748
149 + 981599 = 981748
179 + 981569 = 981748
281 + 981467 = 981748
311 + 981437 = 981748
461 + 981287 = 981748
827 + 980921 = 981748

Showing the first eight; more decompositions exist.
