Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712722, here are decompositions:

13 + 8712709 = 8712722
61 + 8712661 = 8712722
199 + 8712523 = 8712722
349 + 8712373 = 8712722
373 + 8712349 = 8712722
463 + 8712259 = 8712722
541 + 8712181 = 8712722
631 + 8712091 = 8712722

Showing the first eight; more decompositions exist.
