Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499336, here are decompositions:

7 + 31499329 = 31499336
13 + 31499323 = 31499336
97 + 31499239 = 31499336
109 + 31499227 = 31499336
199 + 31499137 = 31499336
229 + 31499107 = 31499336
313 + 31499023 = 31499336
373 + 31498963 = 31499336

Showing the first eight; more decompositions exist.
