Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742776, here are decompositions:

37 + 8742739 = 8742776
103 + 8742673 = 8742776
139 + 8742637 = 8742776
199 + 8742577 = 8742776
277 + 8742499 = 8742776
283 + 8742493 = 8742776
307 + 8742469 = 8742776
313 + 8742463 = 8742776

Showing the first eight; more decompositions exist.
