Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719946, here are decompositions:

3 + 8719943 = 8719946
7 + 8719939 = 8719946
43 + 8719903 = 8719946
73 + 8719873 = 8719946
127 + 8719819 = 8719946
199 + 8719747 = 8719946
283 + 8719663 = 8719946
373 + 8719573 = 8719946

Showing the first eight; more decompositions exist.
