Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009720, here are decompositions:

71 + 1009649 = 1009720
83 + 1009637 = 1009720
233 + 1009487 = 1009720
263 + 1009457 = 1009720
281 + 1009439 = 1009720
347 + 1009373 = 1009720
359 + 1009361 = 1009720
401 + 1009319 = 1009720

Showing the first eight; more decompositions exist.
