Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642230, here are decompositions:

41 + 8642189 = 8642230
71 + 8642159 = 8642230
83 + 8642147 = 8642230
89 + 8642141 = 8642230
131 + 8642099 = 8642230
167 + 8642063 = 8642230
173 + 8642057 = 8642230
197 + 8642033 = 8642230

Showing the first eight; more decompositions exist.
