Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42902, here are decompositions:

3 + 42899 = 42902
43 + 42859 = 42902
61 + 42841 = 42902
73 + 42829 = 42902
109 + 42793 = 42902
151 + 42751 = 42902
193 + 42709 = 42902
199 + 42703 = 42902

Showing the first eight; more decompositions exist.
