Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541538, here are decompositions:

7 + 541531 = 541538
31 + 541507 = 541538
157 + 541381 = 541538
199 + 541339 = 541538
229 + 541309 = 541538
271 + 541267 = 541538
307 + 541231 = 541538
337 + 541201 = 541538

Showing the first eight; more decompositions exist.
