Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522870, here are decompositions:

13 + 522857 = 522870
17 + 522853 = 522870
31 + 522839 = 522870
41 + 522829 = 522870
43 + 522827 = 522870
59 + 522811 = 522870
83 + 522787 = 522870
107 + 522763 = 522870

Showing the first eight; more decompositions exist.
