Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612722, here are decompositions:

11 + 8612711 = 8612722
59 + 8612663 = 8612722
89 + 8612633 = 8612722
191 + 8612531 = 8612722
311 + 8612411 = 8612722
479 + 8612243 = 8612722
683 + 8612039 = 8612722
761 + 8611961 = 8612722

Showing the first eight; more decompositions exist.
