Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 97870, here are decompositions:

11 + 97859 = 97870
23 + 97847 = 97870
29 + 97841 = 97870
41 + 97829 = 97870
83 + 97787 = 97870
197 + 97673 = 97870
257 + 97613 = 97870
263 + 97607 = 97870

Showing the first eight; more decompositions exist.
