Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102572, here are decompositions:

13 + 102559 = 102572
73 + 102499 = 102572
139 + 102433 = 102572
163 + 102409 = 102572
271 + 102301 = 102572
313 + 102259 = 102572
331 + 102241 = 102572
373 + 102199 = 102572

Showing the first eight; more decompositions exist.
