Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642342, here are decompositions:

13 + 8642329 = 8642342
61 + 8642281 = 8642342
223 + 8642119 = 8642342
283 + 8642059 = 8642342
433 + 8641909 = 8642342
523 + 8641819 = 8642342
601 + 8641741 = 8642342
673 + 8641669 = 8642342

Showing the first eight; more decompositions exist.
