Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720626, here are decompositions:

3 + 8720623 = 8720626
29 + 8720597 = 8720626
113 + 8720513 = 8720626
137 + 8720489 = 8720626
149 + 8720477 = 8720626
179 + 8720447 = 8720626
197 + 8720429 = 8720626
449 + 8720177 = 8720626

Showing the first eight; more decompositions exist.
