Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31274, here are decompositions:
- 3 + 31271 = 31274
- 7 + 31267 = 31274
- 37 + 31237 = 31274
- 43 + 31231 = 31274
- 97 + 31177 = 31274
- 127 + 31147 = 31274
- 151 + 31123 = 31274
- 193 + 31081 = 31274
Showing the first eight; more decompositions exist.
