Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022872, here are decompositions:

3 + 1022869 = 1022872
23 + 1022849 = 1022872
29 + 1022843 = 1022872
233 + 1022639 = 1022872
239 + 1022633 = 1022872
281 + 1022591 = 1022872
353 + 1022519 = 1022872
359 + 1022513 = 1022872

Showing the first eight; more decompositions exist.
