Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1025518, here are decompositions:

5 + 1025513 = 1025518
41 + 1025477 = 1025518
59 + 1025459 = 1025518
101 + 1025417 = 1025518
167 + 1025351 = 1025518
191 + 1025327 = 1025518
239 + 1025279 = 1025518
251 + 1025267 = 1025518

Showing the first eight; more decompositions exist.
