Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981498, here are decompositions:

5 + 981493 = 981498
17 + 981481 = 981498
31 + 981467 = 981498
47 + 981451 = 981498
59 + 981439 = 981498
61 + 981437 = 981498
79 + 981419 = 981498
101 + 981397 = 981498

Showing the first eight; more decompositions exist.
