Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642076, here are decompositions:

13 + 8642063 = 8642076
17 + 8642059 = 8642076
19 + 8642057 = 8642076
43 + 8642033 = 8642076
73 + 8642003 = 8642076
89 + 8641987 = 8642076
127 + 8641949 = 8642076
167 + 8641909 = 8642076

Showing the first eight; more decompositions exist.
