Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494790, here are decompositions:

23 + 31494767 = 31494790
53 + 31494737 = 31494790
83 + 31494707 = 31494790
101 + 31494689 = 31494790
179 + 31494611 = 31494790
281 + 31494509 = 31494790
293 + 31494497 = 31494790
311 + 31494479 = 31494790

Showing the first eight; more decompositions exist.
