Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720750, here are decompositions:

37 + 8720713 = 8720750
43 + 8720707 = 8720750
61 + 8720689 = 8720750
79 + 8720671 = 8720750
127 + 8720623 = 8720750
193 + 8720557 = 8720750
271 + 8720479 = 8720750
433 + 8720317 = 8720750

Showing the first eight; more decompositions exist.
