Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541668, here are decompositions:

7 + 541661 = 541668
11 + 541657 = 541668
37 + 541631 = 541668
79 + 541589 = 541668
89 + 541579 = 541668
97 + 541571 = 541668
131 + 541537 = 541668
137 + 541531 = 541668

Showing the first eight; more decompositions exist.
