Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173518, here are decompositions:

17 + 173501 = 173518
89 + 173429 = 173518
227 + 173291 = 173518
251 + 173267 = 173518
269 + 173249 = 173518
311 + 173207 = 173518
419 + 173099 = 173518
431 + 173087 = 173518

Showing the first eight; more decompositions exist.
