Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719722, here are decompositions:

19 + 8719703 = 8719722
23 + 8719699 = 8719722
41 + 8719681 = 8719722
59 + 8719663 = 8719722
61 + 8719661 = 8719722
131 + 8719591 = 8719722
149 + 8719573 = 8719722
173 + 8719549 = 8719722

Showing the first eight; more decompositions exist.
