Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025472, here are decompositions:

13 + 1025459 = 1025472
29 + 1025443 = 1025472
53 + 1025419 = 1025472
59 + 1025413 = 1025472
79 + 1025393 = 1025472
89 + 1025383 = 1025472
139 + 1025333 = 1025472
191 + 1025281 = 1025472

Showing the first eight; more decompositions exist.
