Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494936, here are decompositions:

13 + 31494923 = 31494936
17 + 31494919 = 31494936
29 + 31494907 = 31494936
127 + 31494809 = 31494936
167 + 31494769 = 31494936
173 + 31494763 = 31494936
199 + 31494737 = 31494936
223 + 31494713 = 31494936

Showing the first eight; more decompositions exist.
