Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025818, here are decompositions:

11 + 1025807 = 1025818
29 + 1025789 = 1025818
71 + 1025747 = 1025818
149 + 1025669 = 1025818
197 + 1025621 = 1025818
239 + 1025579 = 1025818
257 + 1025561 = 1025818
281 + 1025537 = 1025818

Showing the first eight; more decompositions exist.
