Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542558, here are decompositions:

7 + 542551 = 542558
19 + 542539 = 542558
61 + 542497 = 542558
97 + 542461 = 542558
157 + 542401 = 542558
277 + 542281 = 542558
307 + 542251 = 542558
409 + 542149 = 542558

Showing the first eight; more decompositions exist.
