Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499822, here are decompositions:

19 + 31499803 = 31499822
61 + 31499761 = 31499822
163 + 31499659 = 31499822
223 + 31499599 = 31499822
229 + 31499593 = 31499822
331 + 31499491 = 31499822
421 + 31499401 = 31499822
439 + 31499383 = 31499822

Showing the first eight; more decompositions exist.
