Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 74158, here are decompositions:

59 + 74099 = 74158
107 + 74051 = 74158
131 + 74027 = 74158
137 + 74021 = 74158
197 + 73961 = 74158
251 + 73907 = 74158
281 + 73877 = 74158
311 + 73847 = 74158

Showing the first eight; more decompositions exist.
