Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757942, here are decompositions:

23 + 8757919 = 8757942
113 + 8757829 = 8757942
173 + 8757769 = 8757942
223 + 8757719 = 8757942
229 + 8757713 = 8757942
241 + 8757701 = 8757942
251 + 8757691 = 8757942
283 + 8757659 = 8757942

Showing the first eight; more decompositions exist.
