Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484192, here are decompositions:

13 + 31484179 = 31484192
31 + 31484161 = 31484192
211 + 31483981 = 31484192
331 + 31483861 = 31484192
373 + 31483819 = 31484192
433 + 31483759 = 31484192
643 + 31483549 = 31484192
739 + 31483453 = 31484192

Showing the first eight; more decompositions exist.
