Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541918, here are decompositions:

17 + 541901 = 541918
29 + 541889 = 541918
59 + 541859 = 541918
101 + 541817 = 541918
137 + 541781 = 541918
191 + 541727 = 541918
197 + 541721 = 541918
257 + 541661 = 541918

Showing the first eight; more decompositions exist.
