Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484644, here are decompositions:

17 + 31484627 = 31484644
101 + 31484543 = 31484644
131 + 31484513 = 31484644
227 + 31484417 = 31484644
281 + 31484363 = 31484644
467 + 31484177 = 31484644
563 + 31484081 = 31484644
761 + 31483883 = 31484644

Showing the first eight; more decompositions exist.
