Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499672, here are decompositions:

13 + 31499659 = 31499672
73 + 31499599 = 31499672
79 + 31499593 = 31499672
181 + 31499491 = 31499672
241 + 31499431 = 31499672
271 + 31499401 = 31499672
331 + 31499341 = 31499672
349 + 31499323 = 31499672

Showing the first eight; more decompositions exist.
