Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484998, here are decompositions:

5 + 31484993 = 31484998
197 + 31484801 = 31484998
227 + 31484771 = 31484998
257 + 31484741 = 31484998
659 + 31484339 = 31484998
761 + 31484237 = 31484998
821 + 31484177 = 31484998
929 + 31484069 = 31484998

Showing the first eight; more decompositions exist.
