Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641602, here are decompositions:

31 + 8641571 = 8641602
59 + 8641543 = 8641602
61 + 8641541 = 8641602
83 + 8641519 = 8641602
89 + 8641513 = 8641602
131 + 8641471 = 8641602
149 + 8641453 = 8641602
173 + 8641429 = 8641602

Showing the first eight; more decompositions exist.
