Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484410, here are decompositions:

47 + 31484363 = 31484410
71 + 31484339 = 31484410
107 + 31484303 = 31484410
173 + 31484237 = 31484410
233 + 31484177 = 31484410
281 + 31484129 = 31484410
317 + 31484093 = 31484410
431 + 31483979 = 31484410

Showing the first eight; more decompositions exist.
