Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541278, here are decompositions:

7 + 541271 = 541278
11 + 541267 = 541278
29 + 541249 = 541278
41 + 541237 = 541278
47 + 541231 = 541278
61 + 541217 = 541278
97 + 541181 = 541278
137 + 541141 = 541278

Showing the first eight; more decompositions exist.
