Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1009190, here are decompositions:

31 + 1009159 = 1009190
37 + 1009153 = 1009190
199 + 1008991 = 1009190
211 + 1008979 = 1009190
277 + 1008913 = 1009190
331 + 1008859 = 1009190
337 + 1008853 = 1009190
373 + 1008817 = 1009190

Showing the first eight; more decompositions exist.
