Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173770, here are decompositions:

29 + 173741 = 173770
41 + 173729 = 173770
71 + 173699 = 173770
83 + 173687 = 173770
101 + 173669 = 173770
197 + 173573 = 173770
227 + 173543 = 173770
239 + 173531 = 173770

Showing the first eight; more decompositions exist.
