Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 563842, here are decompositions:

5 + 563837 = 563842
11 + 563831 = 563842
29 + 563813 = 563842
179 + 563663 = 563842
281 + 563561 = 563842
353 + 563489 = 563842
431 + 563411 = 563842
491 + 563351 = 563842

Showing the first eight; more decompositions exist.
