Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493608, here are decompositions:

89 + 31493519 = 31493608
131 + 31493477 = 31493608
269 + 31493339 = 31493608
317 + 31493291 = 31493608
359 + 31493249 = 31493608
569 + 31493039 = 31493608
599 + 31493009 = 31493608
617 + 31492991 = 31493608

Showing the first eight; more decompositions exist.
