Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77814, here are decompositions:

13 + 77801 = 77814
17 + 77797 = 77814
31 + 77783 = 77814
41 + 77773 = 77814
53 + 77761 = 77814
67 + 77747 = 77814
71 + 77743 = 77814
83 + 77731 = 77814

Showing the first eight; more decompositions exist.
