Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020572, here are decompositions:

31 + 1020541 = 1020572
43 + 1020529 = 1020572
193 + 1020379 = 1020572
211 + 1020361 = 1020572
271 + 1020301 = 1020572
313 + 1020259 = 1020572
349 + 1020223 = 1020572
409 + 1020163 = 1020572

Showing the first eight; more decompositions exist.
