Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 536872, here are decompositions:

3 + 536869 = 536872
5 + 536867 = 536872
23 + 536849 = 536872
71 + 536801 = 536872
101 + 536771 = 536872
173 + 536699 = 536872
239 + 536633 = 536872
251 + 536621 = 536872

Showing the first eight; more decompositions exist.
