Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494598, here are decompositions:

17 + 31494581 = 31494598
89 + 31494509 = 31494598
101 + 31494497 = 31494598
131 + 31494467 = 31494598
167 + 31494431 = 31494598
197 + 31494401 = 31494598
251 + 31494347 = 31494598
419 + 31494179 = 31494598

Showing the first eight; more decompositions exist.
