Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025802, here are decompositions:

13 + 1025789 = 1025802
53 + 1025749 = 1025802
61 + 1025741 = 1025802
109 + 1025693 = 1025802
149 + 1025653 = 1025802
179 + 1025623 = 1025802
181 + 1025621 = 1025802
191 + 1025611 = 1025802

Showing the first eight; more decompositions exist.
