Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493950, here are decompositions:

23 + 31493927 = 31493950
41 + 31493909 = 31493950
167 + 31493783 = 31493950
233 + 31493717 = 31493950
239 + 31493711 = 31493950
431 + 31493519 = 31493950
503 + 31493447 = 31493950
659 + 31493291 = 31493950

Showing the first eight; more decompositions exist.
