Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 70478, here are decompositions:

19 + 70459 = 70478
97 + 70381 = 70478
127 + 70351 = 70478
151 + 70327 = 70478
157 + 70321 = 70478
181 + 70297 = 70478
229 + 70249 = 70478
241 + 70237 = 70478

Showing the first eight; more decompositions exist.
