Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 120660, here are decompositions:

13 + 120647 = 120660
19 + 120641 = 120660
37 + 120623 = 120660
41 + 120619 = 120660
53 + 120607 = 120660
73 + 120587 = 120660
83 + 120577 = 120660
97 + 120563 = 120660

Showing the first eight; more decompositions exist.
