Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157668, here are decompositions:

19 + 157649 = 157668
29 + 157639 = 157668
31 + 157637 = 157668
41 + 157627 = 157668
89 + 157579 = 157668
97 + 157571 = 157668
107 + 157561 = 157668
109 + 157559 = 157668

Showing the first eight; more decompositions exist.
