Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77862, here are decompositions:

13 + 77849 = 77862
23 + 77839 = 77862
61 + 77801 = 77862
79 + 77783 = 77862
89 + 77773 = 77862
101 + 77761 = 77862
131 + 77731 = 77862
139 + 77723 = 77862

Showing the first eight; more decompositions exist.
