Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525156, here are decompositions:

13 + 525143 = 525156
19 + 525137 = 525156
29 + 525127 = 525156
113 + 525043 = 525156
127 + 525029 = 525156
139 + 525017 = 525156
157 + 524999 = 525156
173 + 524983 = 525156

Showing the first eight; more decompositions exist.
