Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541518, here are decompositions:

7 + 541511 = 541518
11 + 541507 = 541518
71 + 541447 = 541518
79 + 541439 = 541518
101 + 541417 = 541518
127 + 541391 = 541518
137 + 541381 = 541518
149 + 541369 = 541518

Showing the first eight; more decompositions exist.
