Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026390, here are decompositions:

7 + 1026383 = 1026390
19 + 1026371 = 1026390
31 + 1026359 = 1026390
59 + 1026331 = 1026390
97 + 1026293 = 1026390
137 + 1026253 = 1026390
139 + 1026251 = 1026390
163 + 1026227 = 1026390

Showing the first eight; more decompositions exist.
