Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151974, here are decompositions:

5 + 151969 = 151974
7 + 151967 = 151974
37 + 151937 = 151974
71 + 151903 = 151974
73 + 151901 = 151974
103 + 151871 = 151974
127 + 151847 = 151974
157 + 151817 = 151974

Showing the first eight; more decompositions exist.
