Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158408, here are decompositions:

37 + 158371 = 158408
67 + 158341 = 158408
79 + 158329 = 158408
139 + 158269 = 158408
181 + 158227 = 158408
199 + 158209 = 158408
331 + 158077 = 158408
337 + 158071 = 158408

Showing the first eight; more decompositions exist.
