Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102492, here are decompositions:

11 + 102481 = 102492
31 + 102461 = 102492
41 + 102451 = 102492
59 + 102433 = 102492
83 + 102409 = 102492
163 + 102329 = 102492
191 + 102301 = 102492
193 + 102299 = 102492

Showing the first eight; more decompositions exist.
