Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025442, here are decompositions:

23 + 1025419 = 1025442
29 + 1025413 = 1025442
59 + 1025383 = 1025442
109 + 1025333 = 1025442
139 + 1025303 = 1025442
163 + 1025279 = 1025442
181 + 1025261 = 1025442
211 + 1025231 = 1025442

Showing the first eight; more decompositions exist.
