Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31619108, here are decompositions:

67 + 31619041 = 31619108
109 + 31618999 = 31619108
127 + 31618981 = 31619108
211 + 31618897 = 31619108
229 + 31618879 = 31619108
331 + 31618777 = 31619108
337 + 31618771 = 31619108
397 + 31618711 = 31619108

Showing the first eight; more decompositions exist.
