Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719622, here are decompositions:

19 + 8719603 = 8719622
31 + 8719591 = 8719622
73 + 8719549 = 8719622
103 + 8719519 = 8719622
139 + 8719483 = 8719622
181 + 8719441 = 8719622
349 + 8719273 = 8719622
409 + 8719213 = 8719622

Showing the first eight; more decompositions exist.
