Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499246, here are decompositions:

7 + 31499239 = 31499246
19 + 31499227 = 31499246
109 + 31499137 = 31499246
139 + 31499107 = 31499246
223 + 31499023 = 31499246
283 + 31498963 = 31499246
349 + 31498897 = 31499246
367 + 31498879 = 31499246

Showing the first eight; more decompositions exist.
