Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025988, here are decompositions:

31 + 1025957 = 1025988
59 + 1025929 = 1025988
71 + 1025917 = 1025988
79 + 1025909 = 1025988
97 + 1025891 = 1025988
101 + 1025887 = 1025988
149 + 1025839 = 1025988
181 + 1025807 = 1025988

Showing the first eight; more decompositions exist.
