Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750, here are decompositions:

3 + 8747 = 8750
13 + 8737 = 8750
19 + 8731 = 8750
31 + 8719 = 8750
37 + 8713 = 8750
43 + 8707 = 8750
61 + 8689 = 8750
73 + 8677 = 8750

Showing the first eight; more decompositions exist.
