Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005880, here are decompositions:

47 + 1005833 = 1005880
53 + 1005827 = 1005880
59 + 1005821 = 1005880
179 + 1005701 = 1005880
233 + 1005647 = 1005880
263 + 1005617 = 1005880
353 + 1005527 = 1005880
443 + 1005437 = 1005880

Showing the first eight; more decompositions exist.
