Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542538, here are decompositions:

5 + 542533 = 542538
19 + 542519 = 542538
41 + 542497 = 542538
71 + 542467 = 542538
97 + 542441 = 542538
137 + 542401 = 542538
167 + 542371 = 542538
239 + 542299 = 542538

Showing the first eight; more decompositions exist.
