Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525072, here are decompositions:

29 + 525043 = 525072
43 + 525029 = 525072
59 + 525013 = 525072
71 + 525001 = 525072
73 + 524999 = 525072
89 + 524983 = 525072
101 + 524971 = 525072
103 + 524969 = 525072

Showing the first eight; more decompositions exist.
