Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715642, here are decompositions:

41 + 8715601 = 8715642
53 + 8715589 = 8715642
83 + 8715559 = 8715642
191 + 8715451 = 8715642
193 + 8715449 = 8715642
211 + 8715431 = 8715642
233 + 8715409 = 8715642
239 + 8715403 = 8715642

Showing the first eight; more decompositions exist.
