Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725906, here are decompositions:

29 + 8725877 = 8725906
83 + 8725823 = 8725906
89 + 8725817 = 8725906
107 + 8725799 = 8725906
149 + 8725757 = 8725906
173 + 8725733 = 8725906
263 + 8725643 = 8725906
359 + 8725547 = 8725906

Showing the first eight; more decompositions exist.
