Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541686, here are decompositions:

17 + 541669 = 541686
29 + 541657 = 541686
73 + 541613 = 541686
97 + 541589 = 541686
107 + 541579 = 541686
109 + 541577 = 541686
137 + 541549 = 541686
139 + 541547 = 541686

Showing the first eight; more decompositions exist.
