Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642344, here are decompositions:

41 + 8642303 = 8642344
107 + 8642237 = 8642344
197 + 8642147 = 8642344
233 + 8642111 = 8642344
281 + 8642063 = 8642344
311 + 8642033 = 8642344
317 + 8642027 = 8642344
353 + 8641991 = 8642344

Showing the first eight; more decompositions exist.
