Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981480, here are decompositions:

7 + 981473 = 981480
13 + 981467 = 981480
29 + 981451 = 981480
37 + 981443 = 981480
41 + 981439 = 981480
43 + 981437 = 981480
61 + 981419 = 981480
83 + 981397 = 981480

Showing the first eight; more decompositions exist.
