Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77888, here are decompositions:

127 + 77761 = 77888
157 + 77731 = 77888
199 + 77689 = 77888
229 + 77659 = 77888
241 + 77647 = 77888
271 + 77617 = 77888
277 + 77611 = 77888
331 + 77557 = 77888

Showing the first eight; more decompositions exist.
