Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2902, here are decompositions:

5 + 2897 = 2902
23 + 2879 = 2902
41 + 2861 = 2902
59 + 2843 = 2902
83 + 2819 = 2902
101 + 2801 = 2902
113 + 2789 = 2902
149 + 2753 = 2902

Showing the first eight; more decompositions exist.
