Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 958990, here are decompositions:

17 + 958973 = 958990
23 + 958967 = 958990
59 + 958931 = 958990
89 + 958901 = 958990
107 + 958883 = 958990
113 + 958877 = 958990
251 + 958739 = 958990
311 + 958679 = 958990

Showing the first eight; more decompositions exist.
