Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019564, here are decompositions:

31 + 1019533 = 1019564
61 + 1019503 = 1019564
97 + 1019467 = 1019564
151 + 1019413 = 1019564
211 + 1019353 = 1019564
283 + 1019281 = 1019564
307 + 1019257 = 1019564
313 + 1019251 = 1019564

Showing the first eight; more decompositions exist.
