Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542488, here are decompositions:

5 + 542483 = 542488
41 + 542447 = 542488
47 + 542441 = 542488
227 + 542261 = 542488
251 + 542237 = 542488
269 + 542219 = 542488
281 + 542207 = 542488
347 + 542141 = 542488

Showing the first eight; more decompositions exist.
