Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021532, here are decompositions:

103 + 1021429 = 1021532
151 + 1021381 = 1021532
163 + 1021369 = 1021532
199 + 1021333 = 1021532
229 + 1021303 = 1021532
241 + 1021291 = 1021532
271 + 1021261 = 1021532
349 + 1021183 = 1021532

Showing the first eight; more decompositions exist.
