Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1007720, here are decompositions:

19 + 1007701 = 1007720
37 + 1007683 = 1007720
73 + 1007647 = 1007720
163 + 1007557 = 1007720
193 + 1007527 = 1007720
223 + 1007497 = 1007720
367 + 1007353 = 1007720
421 + 1007299 = 1007720

Showing the first eight; more decompositions exist.
