Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025604, here are decompositions:

43 + 1025561 = 1025604
53 + 1025551 = 1025604
61 + 1025543 = 1025604
67 + 1025537 = 1025604
101 + 1025503 = 1025604
127 + 1025477 = 1025604
191 + 1025413 = 1025604
197 + 1025407 = 1025604

Showing the first eight; more decompositions exist.
