Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758940, here are decompositions:

7 + 8758933 = 8758940
19 + 8758921 = 8758940
37 + 8758903 = 8758940
61 + 8758879 = 8758940
79 + 8758861 = 8758940
139 + 8758801 = 8758940
163 + 8758777 = 8758940
193 + 8758747 = 8758940

Showing the first eight; more decompositions exist.
