Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981504, here are decompositions:

11 + 981493 = 981504
23 + 981481 = 981504
31 + 981473 = 981504
37 + 981467 = 981504
53 + 981451 = 981504
61 + 981443 = 981504
67 + 981437 = 981504
107 + 981397 = 981504

Showing the first eight; more decompositions exist.
