Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999722, here are decompositions:

109 + 999613 = 999722
181 + 999541 = 999722
193 + 999529 = 999722
223 + 999499 = 999722
271 + 999451 = 999722
523 + 999199 = 999722
541 + 999181 = 999722
631 + 999091 = 999722

Showing the first eight; more decompositions exist.
