Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726722, here are decompositions:

23 + 8726699 = 8726722
89 + 8726633 = 8726722
149 + 8726573 = 8726722
359 + 8726363 = 8726722
449 + 8726273 = 8726722
479 + 8726243 = 8726722
659 + 8726063 = 8726722
701 + 8726021 = 8726722

Showing the first eight; more decompositions exist.
