Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642002, here are decompositions:

11 + 8641991 = 8642002
53 + 8641949 = 8642002
269 + 8641733 = 8642002
293 + 8641709 = 8642002
359 + 8641643 = 8642002
389 + 8641613 = 8642002
431 + 8641571 = 8642002
461 + 8641541 = 8642002

Showing the first eight; more decompositions exist.
