Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115902, here are decompositions:

11 + 115891 = 115902
19 + 115883 = 115902
23 + 115879 = 115902
29 + 115873 = 115902
41 + 115861 = 115902
43 + 115859 = 115902
53 + 115849 = 115902
71 + 115831 = 115902

Showing the first eight; more decompositions exist.
