Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005902, here are decompositions:

19 + 1005883 = 1005902
151 + 1005751 = 1005902
193 + 1005709 = 1005902
223 + 1005679 = 1005902
241 + 1005661 = 1005902
283 + 1005619 = 1005902
349 + 1005553 = 1005902
409 + 1005493 = 1005902

Showing the first eight; more decompositions exist.
