Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173158, here are decompositions:

17 + 173141 = 173158
59 + 173099 = 173158
71 + 173087 = 173158
137 + 173021 = 173158
281 + 172877 = 173158
449 + 172709 = 173158
509 + 172649 = 173158
569 + 172589 = 173158

Showing the first eight; more decompositions exist.
