Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025830, here are decompositions:

11 + 1025819 = 1025830
23 + 1025807 = 1025830
41 + 1025789 = 1025830
83 + 1025747 = 1025830
89 + 1025741 = 1025830
137 + 1025693 = 1025830
251 + 1025579 = 1025830
269 + 1025561 = 1025830

Showing the first eight; more decompositions exist.
