Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484224, here are decompositions:

17 + 31484207 = 31484224
47 + 31484177 = 31484224
131 + 31484093 = 31484224
311 + 31483913 = 31484224
347 + 31483877 = 31484224
353 + 31483871 = 31484224
383 + 31483841 = 31484224
491 + 31483733 = 31484224

Showing the first eight; more decompositions exist.
