Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568462, here are decompositions:

43 + 31568419 = 31568462
109 + 31568353 = 31568462
151 + 31568311 = 31568462
181 + 31568281 = 31568462
241 + 31568221 = 31568462
283 + 31568179 = 31568462
379 + 31568083 = 31568462
421 + 31568041 = 31568462

Showing the first eight; more decompositions exist.
