Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 532138, here are decompositions:

137 + 532001 = 532138
149 + 531989 = 532138
227 + 531911 = 532138
281 + 531857 = 532138
311 + 531827 = 532138
317 + 531821 = 532138
449 + 531689 = 532138
557 + 531581 = 532138

Showing the first eight; more decompositions exist.
