Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497616, here are decompositions:
- 47 + 31497569 = 31497616
- 89 + 31497527 = 31497616
- 149 + 31497467 = 31497616
- 167 + 31497449 = 31497616
- 173 + 31497443 = 31497616
- 257 + 31497359 = 31497616
- 263 + 31497353 = 31497616
- 317 + 31497299 = 31497616
Showing the first eight; more decompositions exist.
