Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 39902, here are decompositions:

19 + 39883 = 39902
61 + 39841 = 39902
73 + 39829 = 39902
103 + 39799 = 39902
193 + 39709 = 39902
199 + 39703 = 39902
223 + 39679 = 39902
271 + 39631 = 39902

Showing the first eight; more decompositions exist.
