Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526740, here are decompositions:

7 + 526733 = 526740
23 + 526717 = 526740
31 + 526709 = 526740
37 + 526703 = 526740
59 + 526681 = 526740
61 + 526679 = 526740
73 + 526667 = 526740
83 + 526657 = 526740

Showing the first eight; more decompositions exist.
