Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757800, here are decompositions:

31 + 8757769 = 8757800
43 + 8757757 = 8757800
109 + 8757691 = 8757800
157 + 8757643 = 8757800
229 + 8757571 = 8757800
277 + 8757523 = 8757800
283 + 8757517 = 8757800
313 + 8757487 = 8757800

Showing the first eight; more decompositions exist.
