Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025590, here are decompositions:

11 + 1025579 = 1025590
29 + 1025561 = 1025590
47 + 1025543 = 1025590
53 + 1025537 = 1025590
107 + 1025483 = 1025590
113 + 1025477 = 1025590
131 + 1025459 = 1025590
173 + 1025417 = 1025590

Showing the first eight; more decompositions exist.
