Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158918, here are decompositions:

37 + 158881 = 158918
127 + 158791 = 158918
157 + 158761 = 158918
271 + 158647 = 158918
307 + 158611 = 158918
337 + 158581 = 158918
367 + 158551 = 158918
499 + 158419 = 158918

Showing the first eight; more decompositions exist.
