Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672622, here are decompositions:

59 + 8672563 = 8672622
61 + 8672561 = 8672622
71 + 8672551 = 8672622
83 + 8672539 = 8672622
103 + 8672519 = 8672622
109 + 8672513 = 8672622
113 + 8672509 = 8672622
139 + 8672483 = 8672622

Showing the first eight; more decompositions exist.
