Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642036, here are decompositions:

3 + 8642033 = 8642036
79 + 8641957 = 8642036
127 + 8641909 = 8642036
163 + 8641873 = 8642036
229 + 8641807 = 8642036
367 + 8641669 = 8642036
433 + 8641603 = 8642036
523 + 8641513 = 8642036

Showing the first eight; more decompositions exist.
