Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667772, here are decompositions:

83 + 8667689 = 8667772
131 + 8667641 = 8667772
233 + 8667539 = 8667772
251 + 8667521 = 8667772
353 + 8667419 = 8667772
359 + 8667413 = 8667772
401 + 8667371 = 8667772
593 + 8667179 = 8667772

Showing the first eight; more decompositions exist.
