Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 541522, here are decompositions:

11 + 541511 = 541522
53 + 541469 = 541522
83 + 541439 = 541522
131 + 541391 = 541522
173 + 541349 = 541522
239 + 541283 = 541522
251 + 541271 = 541522
389 + 541133 = 541522

Showing the first eight; more decompositions exist.
