Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642274, here are decompositions:

37 + 8642237 = 8642274
101 + 8642173 = 8642274
127 + 8642147 = 8642274
163 + 8642111 = 8642274
167 + 8642107 = 8642274
197 + 8642077 = 8642274
211 + 8642063 = 8642274
241 + 8642033 = 8642274

Showing the first eight; more decompositions exist.
