Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68890, here are decompositions:

11 + 68879 = 68890
71 + 68819 = 68890
113 + 68777 = 68890
179 + 68711 = 68890
191 + 68699 = 68890
251 + 68639 = 68890
257 + 68633 = 68890
293 + 68597 = 68890

Showing the first eight; more decompositions exist.
