Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541822, here are decompositions:

5 + 541817 = 541822
23 + 541799 = 541822
41 + 541781 = 541822
59 + 541763 = 541822
101 + 541721 = 541822
191 + 541631 = 541822
233 + 541589 = 541822
251 + 541571 = 541822

Showing the first eight; more decompositions exist.
