Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025912, here are decompositions:

3 + 1025909 = 1025912
73 + 1025839 = 1025912
109 + 1025803 = 1025912
163 + 1025749 = 1025912
271 + 1025641 = 1025912
409 + 1025503 = 1025912
499 + 1025413 = 1025912
631 + 1025281 = 1025912

Showing the first eight; more decompositions exist.
