Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484854, here are decompositions:

17 + 31484837 = 31484854
53 + 31484801 = 31484854
83 + 31484771 = 31484854
101 + 31484753 = 31484854
113 + 31484741 = 31484854
227 + 31484627 = 31484854
311 + 31484543 = 31484854
491 + 31484363 = 31484854

Showing the first eight; more decompositions exist.
