Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464186, here are decompositions:

37 + 31464149 = 31464186
43 + 31464143 = 31464186
107 + 31464079 = 31464186
139 + 31464047 = 31464186
223 + 31463963 = 31464186
227 + 31463959 = 31464186
277 + 31463909 = 31464186
293 + 31463893 = 31464186

Showing the first eight; more decompositions exist.
