Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712662, here are decompositions:

61 + 8712601 = 8712662
139 + 8712523 = 8712662
241 + 8712421 = 8712662
313 + 8712349 = 8712662
433 + 8712229 = 8712662
499 + 8712163 = 8712662
571 + 8712091 = 8712662
643 + 8712019 = 8712662

Showing the first eight; more decompositions exist.
