Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42860, here are decompositions:

7 + 42853 = 42860
19 + 42841 = 42860
31 + 42829 = 42860
67 + 42793 = 42860
73 + 42787 = 42860
109 + 42751 = 42860
151 + 42709 = 42860
157 + 42703 = 42860

Showing the first eight; more decompositions exist.
