Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484428, here are decompositions:

11 + 31484417 = 31484428
89 + 31484339 = 31484428
191 + 31484237 = 31484428
251 + 31484177 = 31484428
347 + 31484081 = 31484428
359 + 31484069 = 31484428
449 + 31483979 = 31484428
509 + 31483919 = 31484428

Showing the first eight; more decompositions exist.
