Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83778, here are decompositions:

5 + 83773 = 83778
17 + 83761 = 83778
41 + 83737 = 83778
59 + 83719 = 83778
61 + 83717 = 83778
89 + 83689 = 83778
137 + 83641 = 83778
139 + 83639 = 83778

Showing the first eight; more decompositions exist.
