Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484512, here are decompositions:

149 + 31484363 = 31484512
173 + 31484339 = 31484512
383 + 31484129 = 31484512
419 + 31484093 = 31484512
431 + 31484081 = 31484512
443 + 31484069 = 31484512
593 + 31483919 = 31484512
599 + 31483913 = 31484512

Showing the first eight; more decompositions exist.
