Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1003642, here are decompositions:

11 + 1003631 = 1003642
23 + 1003619 = 1003642
41 + 1003601 = 1003642
53 + 1003589 = 1003642
173 + 1003469 = 1003642
179 + 1003463 = 1003642
281 + 1003361 = 1003642
293 + 1003349 = 1003642

Showing the first eight; more decompositions exist.
