Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642374, here are decompositions:

71 + 8642303 = 8642374
137 + 8642237 = 8642374
227 + 8642147 = 8642374
233 + 8642141 = 8642374
263 + 8642111 = 8642374
311 + 8642063 = 8642374
317 + 8642057 = 8642374
347 + 8642027 = 8642374

Showing the first eight; more decompositions exist.
