Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025864, here are decompositions:

61 + 1025803 = 1025864
97 + 1025767 = 1025864
157 + 1025707 = 1025864
211 + 1025653 = 1025864
223 + 1025641 = 1025864
241 + 1025623 = 1025864
313 + 1025551 = 1025864
421 + 1025443 = 1025864

Showing the first eight; more decompositions exist.
