Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151902, here are decompositions:

5 + 151897 = 151902
19 + 151883 = 151902
31 + 151871 = 151902
53 + 151849 = 151902
61 + 151841 = 151902
89 + 151813 = 151902
103 + 151799 = 151902
131 + 151771 = 151902

Showing the first eight; more decompositions exist.
