Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 97810, here are decompositions:

23 + 97787 = 97810
137 + 97673 = 97810
197 + 97613 = 97810
227 + 97583 = 97810
233 + 97577 = 97810
239 + 97571 = 97810
257 + 97553 = 97810
263 + 97547 = 97810

Showing the first eight; more decompositions exist.
