Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026572, here are decompositions:

181 + 1026391 = 1026572
241 + 1026331 = 1026572
373 + 1026199 = 1026572
433 + 1026139 = 1026572
499 + 1026073 = 1026572
541 + 1026031 = 1026572
643 + 1025929 = 1026572
661 + 1025911 = 1026572

Showing the first eight; more decompositions exist.
