Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 173380, here are decompositions:

23 + 173357 = 173380
71 + 173309 = 173380
83 + 173297 = 173380
89 + 173291 = 173380
107 + 173273 = 173380
113 + 173267 = 173380
131 + 173249 = 173380
173 + 173207 = 173380

Showing the first eight; more decompositions exist.
