Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102450, here are decompositions:

13 + 102437 = 102450
17 + 102433 = 102450
41 + 102409 = 102450
43 + 102407 = 102450
53 + 102397 = 102450
83 + 102367 = 102450
113 + 102337 = 102450
149 + 102301 = 102450

Showing the first eight; more decompositions exist.
