Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999730, here are decompositions:

3 + 999727 = 999730
47 + 999683 = 999730
59 + 999671 = 999730
107 + 999623 = 999730
131 + 999599 = 999730
167 + 999563 = 999730
239 + 999491 = 999730
293 + 999437 = 999730

Showing the first eight; more decompositions exist.
