Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999698, here are decompositions:

31 + 999667 = 999698
67 + 999631 = 999698
157 + 999541 = 999698
199 + 999499 = 999698
367 + 999331 = 999698
499 + 999199 = 999698
607 + 999091 = 999698
631 + 999067 = 999698

Showing the first eight; more decompositions exist.
