Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999830, here are decompositions:

61 + 999769 = 999830
67 + 999763 = 999830
103 + 999727 = 999830
109 + 999721 = 999830
163 + 999667 = 999830
199 + 999631 = 999830
277 + 999553 = 999830
331 + 999499 = 999830

Showing the first eight; more decompositions exist.
