Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77470, here are decompositions:

23 + 77447 = 77470
53 + 77417 = 77470
101 + 77369 = 77470
131 + 77339 = 77470
179 + 77291 = 77470
191 + 77279 = 77470
227 + 77243 = 77470
233 + 77237 = 77470

Showing the first eight; more decompositions exist.
