Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525126, here are decompositions:

83 + 525043 = 525126
97 + 525029 = 525126
109 + 525017 = 525126
113 + 525013 = 525126
127 + 524999 = 525126
157 + 524969 = 525126
163 + 524963 = 525126
167 + 524959 = 525126

Showing the first eight; more decompositions exist.
