Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601780, here are decompositions:

7 + 8601773 = 8601780
13 + 8601767 = 8601780
37 + 8601743 = 8601780
41 + 8601739 = 8601780
53 + 8601727 = 8601780
73 + 8601707 = 8601780
97 + 8601683 = 8601780
113 + 8601667 = 8601780

Showing the first eight; more decompositions exist.
