Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31473430, here are decompositions:
- 17 + 31473413 = 31473430
- 71 + 31473359 = 31473430
- 167 + 31473263 = 31473430
- 179 + 31473251 = 31473430
- 227 + 31473203 = 31473430
- 239 + 31473191 = 31473430
- 257 + 31473173 = 31473430
- 269 + 31473161 = 31473430
Showing the first eight; more decompositions exist.
