Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51572, here are decompositions:

61 + 51511 = 51572
151 + 51421 = 51572
211 + 51361 = 51572
223 + 51349 = 51572
229 + 51343 = 51572
331 + 51241 = 51572
373 + 51199 = 51572
379 + 51193 = 51572

Showing the first eight; more decompositions exist.
