Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499528, here are decompositions:

31 + 31499497 = 31499528
37 + 31499491 = 31499528
61 + 31499467 = 31499528
97 + 31499431 = 31499528
127 + 31499401 = 31499528
157 + 31499371 = 31499528
199 + 31499329 = 31499528
367 + 31499161 = 31499528

Showing the first eight; more decompositions exist.
