Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531954, here are decompositions:

43 + 531911 = 531954
53 + 531901 = 531954
83 + 531871 = 531954
97 + 531857 = 531954
107 + 531847 = 531954
113 + 531841 = 531954
127 + 531827 = 531954
131 + 531823 = 531954

Showing the first eight; more decompositions exist.
