Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025728, here are decompositions:

59 + 1025669 = 1025728
107 + 1025621 = 1025728
149 + 1025579 = 1025728
167 + 1025561 = 1025728
191 + 1025537 = 1025728
251 + 1025477 = 1025728
269 + 1025459 = 1025728
311 + 1025417 = 1025728

Showing the first eight; more decompositions exist.
