Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1006840, here are decompositions:

41 + 1006799 = 1006840
59 + 1006781 = 1006840
71 + 1006769 = 1006840
89 + 1006751 = 1006840
101 + 1006739 = 1006840
227 + 1006613 = 1006840
251 + 1006589 = 1006840
257 + 1006583 = 1006840

Showing the first eight; more decompositions exist.
