Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981426, here are decompositions:

7 + 981419 = 981426
29 + 981397 = 981426
53 + 981373 = 981426
107 + 981319 = 981426
137 + 981289 = 981426
139 + 981287 = 981426
163 + 981263 = 981426
227 + 981199 = 981426

Showing the first eight; more decompositions exist.
