Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31106, here are decompositions:
- 37 + 31069 = 31106
- 43 + 31063 = 31106
- 67 + 31039 = 31106
- 73 + 31033 = 31106
- 157 + 30949 = 31106
- 277 + 30829 = 31106
- 349 + 30757 = 31106
- 379 + 30727 = 31106
Showing the first eight; more decompositions exist.
