Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726772, here are decompositions:

11 + 8726761 = 8726772
13 + 8726759 = 8726772
59 + 8726713 = 8726772
73 + 8726699 = 8726772
101 + 8726671 = 8726772
139 + 8726633 = 8726772
199 + 8726573 = 8726772
239 + 8726533 = 8726772

Showing the first eight; more decompositions exist.
