Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494658, here are decompositions:

47 + 31494611 = 31494658
149 + 31494509 = 31494658
179 + 31494479 = 31494658
191 + 31494467 = 31494658
227 + 31494431 = 31494658
257 + 31494401 = 31494658
269 + 31494389 = 31494658
311 + 31494347 = 31494658

Showing the first eight; more decompositions exist.
