Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000740, here are decompositions:

17 + 1000723 = 1000740
19 + 1000721 = 1000740
43 + 1000697 = 1000740
61 + 1000679 = 1000740
71 + 1000669 = 1000740
73 + 1000667 = 1000740
89 + 1000651 = 1000740
101 + 1000639 = 1000740

Showing the first eight; more decompositions exist.
