Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025878, here are decompositions:

5 + 1025873 = 1025878
59 + 1025819 = 1025878
71 + 1025807 = 1025878
89 + 1025789 = 1025878
131 + 1025747 = 1025878
137 + 1025741 = 1025878
257 + 1025621 = 1025878
317 + 1025561 = 1025878

Showing the first eight; more decompositions exist.
