Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498736, here are decompositions:

79 + 31498657 = 31498736
97 + 31498639 = 31498736
223 + 31498513 = 31498736
457 + 31498279 = 31498736
463 + 31498273 = 31498736
523 + 31498213 = 31498736
547 + 31498189 = 31498736
613 + 31498123 = 31498736

Showing the first eight; more decompositions exist.
