Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31292, here are decompositions:
- 43 + 31249 = 31292
- 61 + 31231 = 31292
- 73 + 31219 = 31292
- 103 + 31189 = 31292
- 109 + 31183 = 31292
- 139 + 31153 = 31292
- 211 + 31081 = 31292
- 223 + 31069 = 31292
Showing the first eight; more decompositions exist.
