Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719662, here are decompositions:

59 + 8719603 = 8719662
71 + 8719591 = 8719662
89 + 8719573 = 8719662
113 + 8719549 = 8719662
179 + 8719483 = 8719662
241 + 8719421 = 8719662
271 + 8719391 = 8719662
283 + 8719379 = 8719662

Showing the first eight; more decompositions exist.
