Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025854, here are decompositions:

47 + 1025807 = 1025854
107 + 1025747 = 1025854
113 + 1025741 = 1025854
233 + 1025621 = 1025854
293 + 1025561 = 1025854
311 + 1025543 = 1025854
317 + 1025537 = 1025854
461 + 1025393 = 1025854

Showing the first eight; more decompositions exist.
