Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171378, here are decompositions:

37 + 171341 = 171378
61 + 171317 = 171378
79 + 171299 = 171378
107 + 171271 = 171378
127 + 171251 = 171378
199 + 171179 = 171378
211 + 171167 = 171378
331 + 171047 = 171378

Showing the first eight; more decompositions exist.
