Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642006, here are decompositions:

3 + 8642003 = 8642006
19 + 8641987 = 8642006
97 + 8641909 = 8642006
199 + 8641807 = 8642006
223 + 8641783 = 8642006
337 + 8641669 = 8642006
463 + 8641543 = 8642006
487 + 8641519 = 8642006

Showing the first eight; more decompositions exist.
