Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494670, here are decompositions:

59 + 31494611 = 31494670
89 + 31494581 = 31494670
167 + 31494503 = 31494670
173 + 31494497 = 31494670
191 + 31494479 = 31494670
227 + 31494443 = 31494670
239 + 31494431 = 31494670
269 + 31494401 = 31494670

Showing the first eight; more decompositions exist.
