Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482206, here are decompositions:

37 + 31482169 = 31482206
103 + 31482103 = 31482206
109 + 31482097 = 31482206
139 + 31482067 = 31482206
163 + 31482043 = 31482206
193 + 31482013 = 31482206
307 + 31481899 = 31482206
439 + 31481767 = 31482206

Showing the first eight; more decompositions exist.
