Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 76870, here are decompositions:

23 + 76847 = 76870
41 + 76829 = 76870
89 + 76781 = 76870
113 + 76757 = 76870
137 + 76733 = 76870
173 + 76697 = 76870
191 + 76679 = 76870
197 + 76673 = 76870

Showing the first eight; more decompositions exist.
