Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519066, here are decompositions:

17 + 31519049 = 31519066
113 + 31518953 = 31519066
167 + 31518899 = 31519066
197 + 31518869 = 31519066
239 + 31518827 = 31519066
389 + 31518677 = 31519066
419 + 31518647 = 31519066
599 + 31518467 = 31519066

Showing the first eight; more decompositions exist.
