Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005194, here are decompositions:

7 + 1005187 = 1005194
61 + 1005133 = 1005194
181 + 1005013 = 1005194
277 + 1004917 = 1005194
283 + 1004911 = 1005194
397 + 1004797 = 1005194
433 + 1004761 = 1005194
457 + 1004737 = 1005194

Showing the first eight; more decompositions exist.
