Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608584, here are decompositions:

103 + 31608481 = 31608584
157 + 31608427 = 31608584
283 + 31608301 = 31608584
313 + 31608271 = 31608584
367 + 31608217 = 31608584
421 + 31608163 = 31608584
523 + 31608061 = 31608584
547 + 31608037 = 31608584

Showing the first eight; more decompositions exist.
