Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15974, here are decompositions:

3 + 15971 = 15974
37 + 15937 = 15974
61 + 15913 = 15974
67 + 15907 = 15974
73 + 15901 = 15974
97 + 15877 = 15974
151 + 15823 = 15974
157 + 15817 = 15974

Showing the first eight; more decompositions exist.
