Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103902, here are decompositions:

13 + 103889 = 103902
59 + 103843 = 103902
61 + 103841 = 103902
89 + 103813 = 103902
101 + 103801 = 103902
179 + 103723 = 103902
199 + 103703 = 103902
233 + 103669 = 103902

Showing the first eight; more decompositions exist.
