Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 174218, here are decompositions:

61 + 174157 = 174218
97 + 174121 = 174218
127 + 174091 = 174218
139 + 174079 = 174218
151 + 174067 = 174218
157 + 174061 = 174218
199 + 174019 = 174218
211 + 174007 = 174218

Showing the first eight; more decompositions exist.
