Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025586, here are decompositions:

7 + 1025579 = 1025586
43 + 1025543 = 1025586
73 + 1025513 = 1025586
83 + 1025503 = 1025586
103 + 1025483 = 1025586
109 + 1025477 = 1025586
127 + 1025459 = 1025586
167 + 1025419 = 1025586

Showing the first eight; more decompositions exist.
