Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025668, here are decompositions:

47 + 1025621 = 1025668
89 + 1025579 = 1025668
107 + 1025561 = 1025668
131 + 1025537 = 1025668
191 + 1025477 = 1025668
251 + 1025417 = 1025668
317 + 1025351 = 1025668
389 + 1025279 = 1025668

Showing the first eight; more decompositions exist.
