Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742750, here are decompositions:

11 + 8742739 = 8742750
61 + 8742689 = 8742750
73 + 8742677 = 8742750
97 + 8742653 = 8742750
113 + 8742637 = 8742750
127 + 8742623 = 8742750
173 + 8742577 = 8742750
179 + 8742571 = 8742750

Showing the first eight; more decompositions exist.
