Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005790, here are decompositions:

29 + 1005761 = 1005790
89 + 1005701 = 1005790
113 + 1005677 = 1005790
173 + 1005617 = 1005790
197 + 1005593 = 1005790
239 + 1005551 = 1005790
263 + 1005527 = 1005790
353 + 1005437 = 1005790

Showing the first eight; more decompositions exist.
