Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538132, here are decompositions:

5 + 538127 = 538132
11 + 538121 = 538132
53 + 538079 = 538132
59 + 538073 = 538132
83 + 538049 = 538132
113 + 538019 = 538132
131 + 538001 = 538132
191 + 537941 = 538132

Showing the first eight; more decompositions exist.
