Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009642, here are decompositions:

5 + 1009637 = 1009642
41 + 1009601 = 1009642
83 + 1009559 = 1009642
269 + 1009373 = 1009642
281 + 1009361 = 1009642
353 + 1009289 = 1009642
383 + 1009259 = 1009642
443 + 1009199 = 1009642

Showing the first eight; more decompositions exist.
