Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494748, here are decompositions:

11 + 31494737 = 31494748
41 + 31494707 = 31494748
59 + 31494689 = 31494748
137 + 31494611 = 31494748
167 + 31494581 = 31494748
239 + 31494509 = 31494748
251 + 31494497 = 31494748
269 + 31494479 = 31494748

Showing the first eight; more decompositions exist.
