Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712788, here are decompositions:

31 + 8712757 = 8712788
37 + 8712751 = 8712788
61 + 8712727 = 8712788
79 + 8712709 = 8712788
127 + 8712661 = 8712788
211 + 8712577 = 8712788
241 + 8712547 = 8712788
367 + 8712421 = 8712788

Showing the first eight; more decompositions exist.
