Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499244, here are decompositions:

5 + 31499239 = 31499244
13 + 31499231 = 31499244
17 + 31499227 = 31499244
61 + 31499183 = 31499244
83 + 31499161 = 31499244
107 + 31499137 = 31499244
137 + 31499107 = 31499244
167 + 31499077 = 31499244

Showing the first eight; more decompositions exist.
