Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108750, here are decompositions:

11 + 108739 = 108750
23 + 108727 = 108750
41 + 108709 = 108750
43 + 108707 = 108750
73 + 108677 = 108750
101 + 108649 = 108750
107 + 108643 = 108750
113 + 108637 = 108750

Showing the first eight; more decompositions exist.
