Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77844, here are decompositions:

5 + 77839 = 77844
31 + 77813 = 77844
43 + 77801 = 77844
47 + 77797 = 77844
61 + 77783 = 77844
71 + 77773 = 77844
83 + 77761 = 77844
97 + 77747 = 77844

Showing the first eight; more decompositions exist.
