Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499702, here are decompositions:

43 + 31499659 = 31499702
103 + 31499599 = 31499702
109 + 31499593 = 31499702
211 + 31499491 = 31499702
271 + 31499431 = 31499702
331 + 31499371 = 31499702
373 + 31499329 = 31499702
379 + 31499323 = 31499702

Showing the first eight; more decompositions exist.
