Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1026578, here are decompositions:

31 + 1026547 = 1026578
97 + 1026481 = 1026578
139 + 1026439 = 1026578
151 + 1026427 = 1026578
349 + 1026229 = 1026578
379 + 1026199 = 1026578
439 + 1026139 = 1026578
541 + 1026037 = 1026578

Showing the first eight; more decompositions exist.
