Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484182, here are decompositions:

3 + 31484179 = 31484182
5 + 31484177 = 31484182
53 + 31484129 = 31484182
89 + 31484093 = 31484182
101 + 31484081 = 31484182
113 + 31484069 = 31484182
263 + 31483919 = 31484182
269 + 31483913 = 31484182

Showing the first eight; more decompositions exist.
