Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102436, here are decompositions:

3 + 102433 = 102436
29 + 102407 = 102436
107 + 102329 = 102436
137 + 102299 = 102436
233 + 102203 = 102436
239 + 102197 = 102436
359 + 102077 = 102436
449 + 101987 = 102436

Showing the first eight; more decompositions exist.
