Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173818, here are decompositions:

11 + 173807 = 173818
41 + 173777 = 173818
89 + 173729 = 173818
131 + 173687 = 173818
149 + 173669 = 173818
167 + 173651 = 173818
257 + 173561 = 173818
269 + 173549 = 173818

Showing the first eight; more decompositions exist.
