Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 138766, here are decompositions:
- 3 + 138763 = 138766
- 83 + 138683 = 138766
- 137 + 138629 = 138766
- 149 + 138617 = 138766
- 167 + 138599 = 138766
- 179 + 138587 = 138766
- 197 + 138569 = 138766
- 269 + 138497 = 138766
Showing the first eight; more decompositions exist.
