Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77018, here are decompositions:

181 + 76837 = 77018
199 + 76819 = 77018
241 + 76777 = 77018
367 + 76651 = 77018
421 + 76597 = 77018
439 + 76579 = 77018
457 + 76561 = 77018
499 + 76519 = 77018

Showing the first eight; more decompositions exist.
