Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77838, here are decompositions:

37 + 77801 = 77838
41 + 77797 = 77838
107 + 77731 = 77838
127 + 77711 = 77838
139 + 77699 = 77838
149 + 77689 = 77838
151 + 77687 = 77838
157 + 77681 = 77838

Showing the first eight; more decompositions exist.
