Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025782, here are decompositions:

41 + 1025741 = 1025782
89 + 1025693 = 1025782
113 + 1025669 = 1025782
239 + 1025543 = 1025782
269 + 1025513 = 1025782
389 + 1025393 = 1025782
431 + 1025351 = 1025782
449 + 1025333 = 1025782

Showing the first eight; more decompositions exist.
