Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547132, here are decompositions:
- 3 + 31547129 = 31547132
- 31 + 31547101 = 31547132
- 151 + 31546981 = 31547132
- 163 + 31546969 = 31547132
- 223 + 31546909 = 31547132
- 241 + 31546891 = 31547132
- 271 + 31546861 = 31547132
- 373 + 31546759 = 31547132
Showing the first eight; more decompositions exist.
