Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005898, here are decompositions:

71 + 1005827 = 1005898
137 + 1005761 = 1005898
197 + 1005701 = 1005898
251 + 1005647 = 1005898
281 + 1005617 = 1005898
317 + 1005581 = 1005898
347 + 1005551 = 1005898
431 + 1005467 = 1005898

Showing the first eight; more decompositions exist.
