Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541782, here are decompositions:

5 + 541777 = 541782
11 + 541771 = 541782
19 + 541763 = 541782
23 + 541759 = 541782
61 + 541721 = 541782
71 + 541711 = 541782
83 + 541699 = 541782
89 + 541693 = 541782

Showing the first eight; more decompositions exist.
