Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525870, here are decompositions:

31 + 525839 = 525870
53 + 525817 = 525870
61 + 525809 = 525870
89 + 525781 = 525870
97 + 525773 = 525870
101 + 525769 = 525870
131 + 525739 = 525870
139 + 525731 = 525870

Showing the first eight; more decompositions exist.
