Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642368, here are decompositions:

131 + 8642237 = 8642368
179 + 8642189 = 8642368
227 + 8642141 = 8642368
257 + 8642111 = 8642368
269 + 8642099 = 8642368
311 + 8642057 = 8642368
419 + 8641949 = 8642368
587 + 8641781 = 8642368

Showing the first eight; more decompositions exist.
