Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005698, here are decompositions:

19 + 1005679 = 1005698
37 + 1005661 = 1005698
61 + 1005637 = 1005698
79 + 1005619 = 1005698
157 + 1005541 = 1005698
241 + 1005457 = 1005698
271 + 1005427 = 1005698
307 + 1005391 = 1005698

Showing the first eight; more decompositions exist.
