Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018768, here are decompositions:

5 + 1018763 = 1018768
59 + 1018709 = 1018768
71 + 1018697 = 1018768
89 + 1018679 = 1018768
347 + 1018421 = 1018768
431 + 1018337 = 1018768
467 + 1018301 = 1018768
521 + 1018247 = 1018768

Showing the first eight; more decompositions exist.
