Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494046, here are decompositions:

5 + 31494041 = 31494046
47 + 31493999 = 31494046
137 + 31493909 = 31494046
257 + 31493789 = 31494046
263 + 31493783 = 31494046
569 + 31493477 = 31494046
599 + 31493447 = 31494046
797 + 31493249 = 31494046

Showing the first eight; more decompositions exist.
