Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981424, here are decompositions:

5 + 981419 = 981424
47 + 981377 = 981424
113 + 981311 = 981424
137 + 981287 = 981424
251 + 981173 = 981424
347 + 981077 = 981424
401 + 981023 = 981424
461 + 980963 = 981424

Showing the first eight; more decompositions exist.
