Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499294, here are decompositions:

3 + 31499291 = 31499294
67 + 31499227 = 31499294
157 + 31499137 = 31499294
271 + 31499023 = 31499294
331 + 31498963 = 31499294
397 + 31498897 = 31499294
457 + 31498837 = 31499294
823 + 31498471 = 31499294

Showing the first eight; more decompositions exist.
