Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639792, here are decompositions:

13 + 8639779 = 8639792
19 + 8639773 = 8639792
43 + 8639749 = 8639792
79 + 8639713 = 8639792
193 + 8639599 = 8639792
229 + 8639563 = 8639792
241 + 8639551 = 8639792
331 + 8639461 = 8639792

Showing the first eight; more decompositions exist.
