Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981330, here are decompositions:

11 + 981319 = 981330
19 + 981311 = 981330
29 + 981301 = 981330
41 + 981289 = 981330
43 + 981287 = 981330
47 + 981283 = 981330
59 + 981271 = 981330
67 + 981263 = 981330

Showing the first eight; more decompositions exist.
