Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31304, here are decompositions:
- 37 + 31267 = 31304
- 67 + 31237 = 31304
- 73 + 31231 = 31304
- 127 + 31177 = 31304
- 151 + 31153 = 31304
- 157 + 31147 = 31304
- 181 + 31123 = 31304
- 223 + 31081 = 31304
Showing the first eight; more decompositions exist.
