Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750660, here are decompositions:

3 + 8750657 = 8750660
19 + 8750641 = 8750660
109 + 8750551 = 8750660
151 + 8750509 = 8750660
181 + 8750479 = 8750660
283 + 8750377 = 8750660
313 + 8750347 = 8750660
367 + 8750293 = 8750660

Showing the first eight; more decompositions exist.
