Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931572, here are decompositions:

29 + 931543 = 931572
43 + 931529 = 931572
73 + 931499 = 931572
151 + 931421 = 931572
263 + 931309 = 931572
269 + 931303 = 931572
283 + 931289 = 931572
331 + 931241 = 931572

Showing the first eight; more decompositions exist.
