Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156678, here are decompositions:

7 + 156671 = 156678
19 + 156659 = 156678
37 + 156641 = 156678
47 + 156631 = 156678
59 + 156619 = 156678
89 + 156589 = 156678
101 + 156577 = 156678
139 + 156539 = 156678

Showing the first eight; more decompositions exist.
