Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568376, here are decompositions:

19 + 31568357 = 31568376
23 + 31568353 = 31568376
29 + 31568347 = 31568376
43 + 31568333 = 31568376
67 + 31568309 = 31568376
79 + 31568297 = 31568376
89 + 31568287 = 31568376
109 + 31568267 = 31568376

Showing the first eight; more decompositions exist.
