Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8710890, here are decompositions:

43 + 8710847 = 8710890
61 + 8710829 = 8710890
109 + 8710781 = 8710890
157 + 8710733 = 8710890
163 + 8710727 = 8710890
173 + 8710717 = 8710890
191 + 8710699 = 8710890
197 + 8710693 = 8710890

Showing the first eight; more decompositions exist.
