Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472986, here are decompositions:
- 3 + 31472983 = 31472986
- 23 + 31472963 = 31472986
- 59 + 31472927 = 31472986
- 107 + 31472879 = 31472986
- 137 + 31472849 = 31472986
- 173 + 31472813 = 31472986
- 179 + 31472807 = 31472986
- 263 + 31472723 = 31472986
Showing the first eight; more decompositions exist.
