Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758142, here are decompositions:

13 + 8758129 = 8758142
61 + 8758081 = 8758142
139 + 8758003 = 8758142
181 + 8757961 = 8758142
199 + 8757943 = 8758142
223 + 8757919 = 8758142
313 + 8757829 = 8758142
373 + 8757769 = 8758142

Showing the first eight; more decompositions exist.
