Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541578, here are decompositions:

7 + 541571 = 541578
29 + 541549 = 541578
31 + 541547 = 541578
41 + 541537 = 541578
47 + 541531 = 541578
67 + 541511 = 541578
71 + 541507 = 541578
109 + 541469 = 541578

Showing the first eight; more decompositions exist.
