Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025842, here are decompositions:

3 + 1025839 = 1025842
23 + 1025819 = 1025842
53 + 1025789 = 1025842
101 + 1025741 = 1025842
149 + 1025693 = 1025842
173 + 1025669 = 1025842
263 + 1025579 = 1025842
281 + 1025561 = 1025842

Showing the first eight; more decompositions exist.
