Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005788, here are decompositions:

37 + 1005751 = 1005788
79 + 1005709 = 1005788
109 + 1005679 = 1005788
127 + 1005661 = 1005788
151 + 1005637 = 1005788
307 + 1005481 = 1005788
331 + 1005457 = 1005788
349 + 1005439 = 1005788

Showing the first eight; more decompositions exist.
