Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725902, here are decompositions:

61 + 8725841 = 8725902
71 + 8725831 = 8725902
79 + 8725823 = 8725902
89 + 8725813 = 8725902
103 + 8725799 = 8725902
233 + 8725669 = 8725902
271 + 8725631 = 8725902
281 + 8725621 = 8725902

Showing the first eight; more decompositions exist.
