Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719632, here are decompositions:

29 + 8719603 = 8719632
41 + 8719591 = 8719632
59 + 8719573 = 8719632
83 + 8719549 = 8719632
113 + 8719519 = 8719632
149 + 8719483 = 8719632
191 + 8719441 = 8719632
211 + 8719421 = 8719632

Showing the first eight; more decompositions exist.
