Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102472, here are decompositions:

11 + 102461 = 102472
113 + 102359 = 102472
173 + 102299 = 102472
179 + 102293 = 102472
239 + 102233 = 102472
269 + 102203 = 102472
281 + 102191 = 102472
311 + 102161 = 102472

Showing the first eight; more decompositions exist.
