Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156630, here are decompositions:

7 + 156623 = 156630
11 + 156619 = 156630
29 + 156601 = 156630
37 + 156593 = 156630
41 + 156589 = 156630
53 + 156577 = 156630
109 + 156521 = 156630
137 + 156493 = 156630

Showing the first eight; more decompositions exist.
