Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001898, here are decompositions:

59 + 1001839 = 1001898
67 + 1001831 = 1001898
89 + 1001809 = 1001898
97 + 1001801 = 1001898
101 + 1001797 = 1001898
211 + 1001687 = 1001898
229 + 1001669 = 1001898
239 + 1001659 = 1001898

Showing the first eight; more decompositions exist.
