Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77668, here are decompositions:

47 + 77621 = 77668
179 + 77489 = 77668
191 + 77477 = 77668
197 + 77471 = 77668
251 + 77417 = 77668
317 + 77351 = 77668
389 + 77279 = 77668
401 + 77267 = 77668

Showing the first eight; more decompositions exist.
