Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8692890, here are decompositions:

13 + 8692877 = 8692890
61 + 8692829 = 8692890
71 + 8692819 = 8692890
83 + 8692807 = 8692890
97 + 8692793 = 8692890
131 + 8692759 = 8692890
163 + 8692727 = 8692890
179 + 8692711 = 8692890

Showing the first eight; more decompositions exist.
