Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 487826, here are decompositions:

7 + 487819 = 487826
37 + 487789 = 487826
43 + 487783 = 487826
109 + 487717 = 487826
223 + 487603 = 487826
337 + 487489 = 487826
349 + 487477 = 487826
379 + 487447 = 487826

Showing the first eight; more decompositions exist.
