Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8562, here are decompositions:

19 + 8543 = 8562
23 + 8539 = 8562
41 + 8521 = 8562
61 + 8501 = 8562
101 + 8461 = 8562
131 + 8431 = 8562
139 + 8423 = 8562
173 + 8389 = 8562

Showing the first eight; more decompositions exist.
