Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005890, here are decompositions:

7 + 1005883 = 1005890
139 + 1005751 = 1005890
181 + 1005709 = 1005890
211 + 1005679 = 1005890
229 + 1005661 = 1005890
271 + 1005619 = 1005890
337 + 1005553 = 1005890
349 + 1005541 = 1005890

Showing the first eight; more decompositions exist.
