Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000720, here are decompositions:

23 + 1000697 = 1000720
29 + 1000691 = 1000720
41 + 1000679 = 1000720
53 + 1000667 = 1000720
101 + 1000619 = 1000720
131 + 1000589 = 1000720
173 + 1000547 = 1000720
179 + 1000541 = 1000720

Showing the first eight; more decompositions exist.
