Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484170, here are decompositions:

41 + 31484129 = 31484170
89 + 31484081 = 31484170
101 + 31484069 = 31484170
191 + 31483979 = 31484170
251 + 31483919 = 31484170
257 + 31483913 = 31484170
281 + 31483889 = 31484170
293 + 31483877 = 31484170

Showing the first eight; more decompositions exist.
