Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494826, here are decompositions:

17 + 31494809 = 31494826
59 + 31494767 = 31494826
89 + 31494737 = 31494826
113 + 31494713 = 31494826
137 + 31494689 = 31494826
317 + 31494509 = 31494826
347 + 31494479 = 31494826
359 + 31494467 = 31494826

Showing the first eight; more decompositions exist.
