Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542532, here are decompositions:

13 + 542519 = 542532
43 + 542489 = 542532
71 + 542461 = 542532
131 + 542401 = 542532
233 + 542299 = 542532
239 + 542293 = 542532
251 + 542281 = 542532
269 + 542263 = 542532

Showing the first eight; more decompositions exist.
