Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101902, here are decompositions:

11 + 101891 = 101902
23 + 101879 = 101902
29 + 101873 = 101902
113 + 101789 = 101902
131 + 101771 = 101902
179 + 101723 = 101902
239 + 101663 = 101902
389 + 101513 = 101902

Showing the first eight; more decompositions exist.
