Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542492, here are decompositions:

3 + 542489 = 542492
31 + 542461 = 542492
193 + 542299 = 542492
199 + 542293 = 542492
211 + 542281 = 542492
229 + 542263 = 542492
241 + 542251 = 542492
373 + 542119 = 542492

Showing the first eight; more decompositions exist.
