Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494196, here are decompositions:

17 + 31494179 = 31494196
53 + 31494143 = 31494196
113 + 31494083 = 31494196
197 + 31493999 = 31494196
269 + 31493927 = 31494196
479 + 31493717 = 31494196
677 + 31493519 = 31494196
683 + 31493513 = 31494196

Showing the first eight; more decompositions exist.
