Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026530, here are decompositions:

73 + 1026457 = 1026530
103 + 1026427 = 1026530
139 + 1026391 = 1026530
199 + 1026331 = 1026530
277 + 1026253 = 1026530
313 + 1026217 = 1026530
331 + 1026199 = 1026530
457 + 1026073 = 1026530

Showing the first eight; more decompositions exist.
