Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102372, here are decompositions:

5 + 102367 = 102372
13 + 102359 = 102372
43 + 102329 = 102372
71 + 102301 = 102372
73 + 102299 = 102372
79 + 102293 = 102372
113 + 102259 = 102372
131 + 102241 = 102372

Showing the first eight; more decompositions exist.
