Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468194, here are decompositions:

47 + 31468147 = 31468194
97 + 31468097 = 31468194
127 + 31468067 = 31468194
167 + 31468027 = 31468194
181 + 31468013 = 31468194
193 + 31468001 = 31468194
211 + 31467983 = 31468194
227 + 31467967 = 31468194

Showing the first eight; more decompositions exist.
