Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494526, here are decompositions:

17 + 31494509 = 31494526
23 + 31494503 = 31494526
29 + 31494497 = 31494526
47 + 31494479 = 31494526
59 + 31494467 = 31494526
83 + 31494443 = 31494526
137 + 31494389 = 31494526
179 + 31494347 = 31494526

Showing the first eight; more decompositions exist.
