Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 78170, here are decompositions:

3 + 78167 = 78170
7 + 78163 = 78170
13 + 78157 = 78170
31 + 78139 = 78170
139 + 78031 = 78170
163 + 78007 = 78170
193 + 77977 = 78170
241 + 77929 = 78170

Showing the first eight; more decompositions exist.
