Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542528, here are decompositions:

31 + 542497 = 542528
61 + 542467 = 542528
67 + 542461 = 542528
127 + 542401 = 542528
157 + 542371 = 542528
229 + 542299 = 542528
277 + 542251 = 542528
331 + 542197 = 542528

Showing the first eight; more decompositions exist.
