Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009978, here are decompositions:

41 + 1009937 = 1009978
191 + 1009787 = 1009978
197 + 1009781 = 1009978
251 + 1009727 = 1009978
419 + 1009559 = 1009978
479 + 1009499 = 1009978
491 + 1009487 = 1009978
521 + 1009457 = 1009978

Showing the first eight; more decompositions exist.
