Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541542, here are decompositions:

5 + 541537 = 541542
11 + 541531 = 541542
13 + 541529 = 541542
19 + 541523 = 541542
31 + 541511 = 541542
59 + 541483 = 541542
73 + 541469 = 541542
103 + 541439 = 541542

Showing the first eight; more decompositions exist.
