Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021604, here are decompositions:

43 + 1021561 = 1021604
163 + 1021441 = 1021604
223 + 1021381 = 1021604
271 + 1021333 = 1021604
277 + 1021327 = 1021604
307 + 1021297 = 1021604
313 + 1021291 = 1021604
421 + 1021183 = 1021604

Showing the first eight; more decompositions exist.
