Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981462, here are decompositions:

11 + 981451 = 981462
19 + 981443 = 981462
23 + 981439 = 981462
43 + 981419 = 981462
71 + 981391 = 981462
89 + 981373 = 981462
151 + 981311 = 981462
173 + 981289 = 981462

Showing the first eight; more decompositions exist.
