Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102402, here are decompositions:

5 + 102397 = 102402
43 + 102359 = 102402
73 + 102329 = 102402
101 + 102301 = 102402
103 + 102299 = 102402
109 + 102293 = 102402
149 + 102253 = 102402
151 + 102251 = 102402

Showing the first eight; more decompositions exist.
