Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8759990, here are decompositions:

13 + 8759977 = 8759990
37 + 8759953 = 8759990
139 + 8759851 = 8759990
193 + 8759797 = 8759990
229 + 8759761 = 8759990
241 + 8759749 = 8759990
313 + 8759677 = 8759990
409 + 8759581 = 8759990

Showing the first eight; more decompositions exist.
