Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608482, here are decompositions:

163 + 31608319 = 31608482
181 + 31608301 = 31608482
211 + 31608271 = 31608482
313 + 31608169 = 31608482
349 + 31608133 = 31608482
421 + 31608061 = 31608482
613 + 31607869 = 31608482
643 + 31607839 = 31608482

Showing the first eight; more decompositions exist.
