Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157974, here are decompositions:

23 + 157951 = 157974
41 + 157933 = 157974
43 + 157931 = 157974
67 + 157907 = 157974
73 + 157901 = 157974
97 + 157877 = 157974
107 + 157867 = 157974
137 + 157837 = 157974

Showing the first eight; more decompositions exist.
