Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1040420, here are decompositions:

13 + 1040407 = 1040420
67 + 1040353 = 1040420
109 + 1040311 = 1040420
193 + 1040227 = 1040420
229 + 1040191 = 1040420
307 + 1040113 = 1040420
331 + 1040089 = 1040420
349 + 1040071 = 1040420

Showing the first eight; more decompositions exist.
