Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001772, here are decompositions:

29 + 1001743 = 1001772
59 + 1001713 = 1001772
89 + 1001683 = 1001772
103 + 1001669 = 1001772
113 + 1001659 = 1001772
151 + 1001621 = 1001772
179 + 1001593 = 1001772
223 + 1001549 = 1001772

Showing the first eight; more decompositions exist.
