Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484260, here are decompositions:

23 + 31484237 = 31484260
53 + 31484207 = 31484260
83 + 31484177 = 31484260
131 + 31484129 = 31484260
167 + 31484093 = 31484260
179 + 31484081 = 31484260
191 + 31484069 = 31484260
281 + 31483979 = 31484260

Showing the first eight; more decompositions exist.
