Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523616, here are decompositions:
- 17 + 31523599 = 31523616
- 37 + 31523579 = 31523616
- 79 + 31523537 = 31523616
- 139 + 31523477 = 31523616
- 149 + 31523467 = 31523616
- 197 + 31523419 = 31523616
- 269 + 31523347 = 31523616
- 307 + 31523309 = 31523616
Showing the first eight; more decompositions exist.
