Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000572, here are decompositions:

31 + 1000541 = 1000572
149 + 1000423 = 1000572
163 + 1000409 = 1000572
179 + 1000393 = 1000572
191 + 1000381 = 1000572
239 + 1000333 = 1000572
269 + 1000303 = 1000572
281 + 1000291 = 1000572

Showing the first eight; more decompositions exist.
