Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85772, here are decompositions:

61 + 85711 = 85772
103 + 85669 = 85772
151 + 85621 = 85772
223 + 85549 = 85772
241 + 85531 = 85772
409 + 85363 = 85772
439 + 85333 = 85772
571 + 85201 = 85772

Showing the first eight; more decompositions exist.
