Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28902, here are decompositions:

23 + 28879 = 28902
31 + 28871 = 28902
43 + 28859 = 28902
59 + 28843 = 28902
89 + 28813 = 28902
109 + 28793 = 28902
113 + 28789 = 28902
131 + 28771 = 28902

Showing the first eight; more decompositions exist.
