Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494796, here are decompositions:

29 + 31494767 = 31494796
59 + 31494737 = 31494796
83 + 31494713 = 31494796
89 + 31494707 = 31494796
107 + 31494689 = 31494796
293 + 31494503 = 31494796
317 + 31494479 = 31494796
353 + 31494443 = 31494796

Showing the first eight; more decompositions exist.
