Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494798, here are decompositions:

17 + 31494781 = 31494798
29 + 31494769 = 31494798
31 + 31494767 = 31494798
61 + 31494737 = 31494798
107 + 31494691 = 31494798
109 + 31494689 = 31494798
331 + 31494467 = 31494798
359 + 31494439 = 31494798

Showing the first eight; more decompositions exist.
