Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568026, here are decompositions:

5 + 31568021 = 31568026
167 + 31567859 = 31568026
257 + 31567769 = 31568026
317 + 31567709 = 31568026
353 + 31567673 = 31568026
383 + 31567643 = 31568026
389 + 31567637 = 31568026
467 + 31567559 = 31568026

Showing the first eight; more decompositions exist.
