Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31599376, here are decompositions:

23 + 31599353 = 31599376
317 + 31599059 = 31599376
443 + 31598933 = 31599376
449 + 31598927 = 31599376
467 + 31598909 = 31599376
503 + 31598873 = 31599376
509 + 31598867 = 31599376
587 + 31598789 = 31599376

Showing the first eight; more decompositions exist.
