Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77516, here are decompositions:

3 + 77513 = 77516
7 + 77509 = 77516
37 + 77479 = 77516
97 + 77419 = 77516
139 + 77377 = 77516
157 + 77359 = 77516
193 + 77323 = 77516
199 + 77317 = 77516

Showing the first eight; more decompositions exist.
