Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641826, here are decompositions:

7 + 8641819 = 8641826
19 + 8641807 = 8641826
43 + 8641783 = 8641826
79 + 8641747 = 8641826
157 + 8641669 = 8641826
223 + 8641603 = 8641826
283 + 8641543 = 8641826
307 + 8641519 = 8641826

Showing the first eight; more decompositions exist.
