Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005980, here are decompositions:

43 + 1005937 = 1005980
67 + 1005913 = 1005980
97 + 1005883 = 1005980
229 + 1005751 = 1005980
271 + 1005709 = 1005980
337 + 1005643 = 1005980
439 + 1005541 = 1005980
487 + 1005493 = 1005980

Showing the first eight; more decompositions exist.
