Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642330, here are decompositions:

157 + 8642173 = 8642330
211 + 8642119 = 8642330
223 + 8642107 = 8642330
271 + 8642059 = 8642330
373 + 8641957 = 8642330
421 + 8641909 = 8642330
439 + 8641891 = 8642330
457 + 8641873 = 8642330

Showing the first eight; more decompositions exist.
