Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127870, here are decompositions:

3 + 127867 = 127870
11 + 127859 = 127870
53 + 127817 = 127870
89 + 127781 = 127870
107 + 127763 = 127870
131 + 127739 = 127870
137 + 127733 = 127870
167 + 127703 = 127870

Showing the first eight; more decompositions exist.
