Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484638, here are decompositions:

11 + 31484627 = 31484638
401 + 31484237 = 31484638
431 + 31484207 = 31484638
461 + 31484177 = 31484638
509 + 31484129 = 31484638
557 + 31484081 = 31484638
569 + 31484069 = 31484638
659 + 31483979 = 31484638

Showing the first eight; more decompositions exist.
