Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 527142, here are decompositions:

13 + 527129 = 527142
19 + 527123 = 527142
43 + 527099 = 527142
61 + 527081 = 527142
71 + 527071 = 527142
73 + 527069 = 527142
79 + 527063 = 527142
89 + 527053 = 527142

Showing the first eight; more decompositions exist.
