Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025486, here are decompositions:

3 + 1025483 = 1025486
43 + 1025443 = 1025486
67 + 1025419 = 1025486
73 + 1025413 = 1025486
79 + 1025407 = 1025486
103 + 1025383 = 1025486
139 + 1025347 = 1025486
229 + 1025257 = 1025486

Showing the first eight; more decompositions exist.
