Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484992, here are decompositions:

3 + 31484989 = 31484992
89 + 31484903 = 31484992
191 + 31484801 = 31484992
239 + 31484753 = 31484992
251 + 31484741 = 31484992
281 + 31484711 = 31484992
293 + 31484699 = 31484992
449 + 31484543 = 31484992

Showing the first eight; more decompositions exist.
