Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76900, here are decompositions:

17 + 76883 = 76900
29 + 76871 = 76900
53 + 76847 = 76900
71 + 76829 = 76900
167 + 76733 = 76900
227 + 76673 = 76900
233 + 76667 = 76900
251 + 76649 = 76900

Showing the first eight; more decompositions exist.
