Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 97780, here are decompositions:

3 + 97777 = 97780
107 + 97673 = 97780
131 + 97649 = 97780
167 + 97613 = 97780
173 + 97607 = 97780
197 + 97583 = 97780
227 + 97553 = 97780
233 + 97547 = 97780

Showing the first eight; more decompositions exist.
