Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720652, here are decompositions:

23 + 8720629 = 8720652
29 + 8720623 = 8720652
71 + 8720581 = 8720652
139 + 8720513 = 8720652
163 + 8720489 = 8720652
173 + 8720479 = 8720652
181 + 8720471 = 8720652
223 + 8720429 = 8720652

Showing the first eight; more decompositions exist.
