Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621792, here are decompositions:

13 + 8621779 = 8621792
19 + 8621773 = 8621792
43 + 8621749 = 8621792
139 + 8621653 = 8621792
211 + 8621581 = 8621792
241 + 8621551 = 8621792
313 + 8621479 = 8621792
349 + 8621443 = 8621792

Showing the first eight; more decompositions exist.
