Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542512, here are decompositions:

23 + 542489 = 542512
29 + 542483 = 542512
71 + 542441 = 542512
251 + 542261 = 542512
293 + 542219 = 542512
359 + 542153 = 542512
389 + 542123 = 542512
401 + 542111 = 542512

Showing the first eight; more decompositions exist.
