Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499708, here are decompositions:

109 + 31499599 = 31499708
211 + 31499497 = 31499708
241 + 31499467 = 31499708
277 + 31499431 = 31499708
307 + 31499401 = 31499708
337 + 31499371 = 31499708
367 + 31499341 = 31499708
379 + 31499329 = 31499708

Showing the first eight; more decompositions exist.
