Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642364, here are decompositions:

61 + 8642303 = 8642364
83 + 8642281 = 8642364
127 + 8642237 = 8642364
167 + 8642197 = 8642364
191 + 8642173 = 8642364
223 + 8642141 = 8642364
257 + 8642107 = 8642364
307 + 8642057 = 8642364

Showing the first eight; more decompositions exist.
