Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497464, here are decompositions:
- 3 + 31497461 = 31497464
- 73 + 31497391 = 31497464
- 127 + 31497337 = 31497464
- 151 + 31497313 = 31497464
- 181 + 31497283 = 31497464
- 241 + 31497223 = 31497464
- 277 + 31497187 = 31497464
- 307 + 31497157 = 31497464
Showing the first eight; more decompositions exist.
