Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025370, here are decompositions:

19 + 1025351 = 1025370
23 + 1025347 = 1025370
37 + 1025333 = 1025370
43 + 1025327 = 1025370
67 + 1025303 = 1025370
89 + 1025281 = 1025370
97 + 1025273 = 1025370
103 + 1025267 = 1025370

Showing the first eight; more decompositions exist.
