Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31006, here are decompositions:
- 23 + 30983 = 31006
- 29 + 30977 = 31006
- 113 + 30893 = 31006
- 137 + 30869 = 31006
- 167 + 30839 = 31006
- 197 + 30809 = 31006
- 233 + 30773 = 31006
- 293 + 30713 = 31006
Showing the first eight; more decompositions exist.
