Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608650, here are decompositions:

61 + 31608589 = 31608650
223 + 31608427 = 31608650
313 + 31608337 = 31608650
331 + 31608319 = 31608650
349 + 31608301 = 31608650
379 + 31608271 = 31608650
433 + 31608217 = 31608650
487 + 31608163 = 31608650

Showing the first eight; more decompositions exist.
