Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008742, here are decompositions:

23 + 1008719 = 1008742
41 + 1008701 = 1008742
83 + 1008659 = 1008742
131 + 1008611 = 1008742
179 + 1008563 = 1008742
239 + 1008503 = 1008742
389 + 1008353 = 1008742
419 + 1008323 = 1008742

Showing the first eight; more decompositions exist.
