Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521008, here are decompositions:

41 + 520967 = 521008
167 + 520841 = 521008
317 + 520691 = 521008
359 + 520649 = 521008
401 + 520607 = 521008
419 + 520589 = 521008
461 + 520547 = 521008
479 + 520529 = 521008

Showing the first eight; more decompositions exist.
