Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525154, here are decompositions:

11 + 525143 = 525154
17 + 525137 = 525154
53 + 525101 = 525154
137 + 525017 = 525154
173 + 524981 = 525154
191 + 524963 = 525154
197 + 524957 = 525154
233 + 524921 = 525154

Showing the first eight; more decompositions exist.
