Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541980, here are decompositions:

13 + 541967 = 541980
29 + 541951 = 541980
53 + 541927 = 541980
79 + 541901 = 541980
149 + 541831 = 541980
163 + 541817 = 541980
181 + 541799 = 541980
199 + 541781 = 541980

Showing the first eight; more decompositions exist.
