Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484866, here are decompositions:

3 + 31484863 = 31484866
29 + 31484837 = 31484866
89 + 31484777 = 31484866
113 + 31484753 = 31484866
167 + 31484699 = 31484866
239 + 31484627 = 31484866
353 + 31484513 = 31484866
449 + 31484417 = 31484866

Showing the first eight; more decompositions exist.
