Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77078, here are decompositions:

31 + 77047 = 77078
37 + 77041 = 77078
61 + 77017 = 77078
241 + 76837 = 77078
277 + 76801 = 77078
307 + 76771 = 77078
499 + 76579 = 77078
541 + 76537 = 77078

Showing the first eight; more decompositions exist.
