Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981562, here are decompositions:

89 + 981473 = 981562
251 + 981311 = 981562
353 + 981209 = 981562
389 + 981173 = 981562
563 + 980999 = 981562
599 + 980963 = 981562
641 + 980921 = 981562
653 + 980909 = 981562

Showing the first eight; more decompositions exist.
