Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608260, here are decompositions:

43 + 31608217 = 31608260
97 + 31608163 = 31608260
127 + 31608133 = 31608260
193 + 31608067 = 31608260
199 + 31608061 = 31608260
223 + 31608037 = 31608260
421 + 31607839 = 31608260
571 + 31607689 = 31608260

Showing the first eight; more decompositions exist.
