Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499374, here are decompositions:

3 + 31499371 = 31499374
47 + 31499327 = 31499374
83 + 31499291 = 31499374
107 + 31499267 = 31499374
191 + 31499183 = 31499374
311 + 31499063 = 31499374
317 + 31499057 = 31499374
353 + 31499021 = 31499374

Showing the first eight; more decompositions exist.
