Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 120678, here are decompositions:

7 + 120671 = 120678
17 + 120661 = 120678
31 + 120647 = 120678
37 + 120641 = 120678
59 + 120619 = 120678
71 + 120607 = 120678
101 + 120577 = 120678
109 + 120569 = 120678

Showing the first eight; more decompositions exist.
