Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1058890, here are decompositions:

29 + 1058861 = 1058890
83 + 1058807 = 1058890
137 + 1058753 = 1058890
167 + 1058723 = 1058890
179 + 1058711 = 1058890
197 + 1058693 = 1058890
227 + 1058663 = 1058890
233 + 1058657 = 1058890

Showing the first eight; more decompositions exist.
