Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541660, here are decompositions:

3 + 541657 = 541660
29 + 541631 = 541660
47 + 541613 = 541660
71 + 541589 = 541660
83 + 541577 = 541660
89 + 541571 = 541660
113 + 541547 = 541660
131 + 541529 = 541660

Showing the first eight; more decompositions exist.
