Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568482, here are decompositions:

59 + 31568423 = 31568482
83 + 31568399 = 31568482
89 + 31568393 = 31568482
149 + 31568333 = 31568482
173 + 31568309 = 31568482
353 + 31568129 = 31568482
359 + 31568123 = 31568482
461 + 31568021 = 31568482

Showing the first eight; more decompositions exist.
