Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542526, here are decompositions:

7 + 542519 = 542526
29 + 542497 = 542526
37 + 542489 = 542526
43 + 542483 = 542526
59 + 542467 = 542526
79 + 542447 = 542526
227 + 542299 = 542526
233 + 542293 = 542526

Showing the first eight; more decompositions exist.
