Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499366, here are decompositions:

37 + 31499329 = 31499366
43 + 31499323 = 31499366
127 + 31499239 = 31499366
139 + 31499227 = 31499366
229 + 31499137 = 31499366
373 + 31498993 = 31499366
487 + 31498879 = 31499366
499 + 31498867 = 31499366

Showing the first eight; more decompositions exist.
