Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77782, here are decompositions:

59 + 77723 = 77782
71 + 77711 = 77782
83 + 77699 = 77782
101 + 77681 = 77782
191 + 77591 = 77782
233 + 77549 = 77782
239 + 77543 = 77782
269 + 77513 = 77782

Showing the first eight; more decompositions exist.
