Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1048440, here are decompositions:

7 + 1048433 = 1048440
17 + 1048423 = 1048440
53 + 1048387 = 1048440
73 + 1048367 = 1048440
79 + 1048361 = 1048440
83 + 1048357 = 1048440
97 + 1048343 = 1048440
131 + 1048309 = 1048440

Showing the first eight; more decompositions exist.
