Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642026, here are decompositions:

23 + 8642003 = 8642026
293 + 8641733 = 8642026
317 + 8641709 = 8642026
353 + 8641673 = 8642026
383 + 8641643 = 8642026
479 + 8641547 = 8642026
509 + 8641517 = 8642026
557 + 8641469 = 8642026

Showing the first eight; more decompositions exist.
