Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608246, here are decompositions:

29 + 31608217 = 31608246
79 + 31608167 = 31608246
83 + 31608163 = 31608246
97 + 31608149 = 31608246
113 + 31608133 = 31608246
139 + 31608107 = 31608246
179 + 31608067 = 31608246
199 + 31608047 = 31608246

Showing the first eight; more decompositions exist.
