Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601642, here are decompositions:

11 + 8601631 = 8601642
13 + 8601629 = 8601642
61 + 8601581 = 8601642
73 + 8601569 = 8601642
131 + 8601511 = 8601642
139 + 8601503 = 8601642
151 + 8601491 = 8601642
193 + 8601449 = 8601642

Showing the first eight; more decompositions exist.
