Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8720892, here are decompositions:

53 + 8720839 = 8720892
73 + 8720819 = 8720892
83 + 8720809 = 8720892
109 + 8720783 = 8720892
163 + 8720729 = 8720892
179 + 8720713 = 8720892
199 + 8720693 = 8720892
211 + 8720681 = 8720892

Showing the first eight; more decompositions exist.
