Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543174, here are decompositions:
- 11 + 31543163 = 31543174
- 41 + 31543133 = 31543174
- 71 + 31543103 = 31543174
- 107 + 31543067 = 31543174
- 233 + 31542941 = 31543174
- 263 + 31542911 = 31543174
- 293 + 31542881 = 31543174
- 317 + 31542857 = 31543174
Showing the first eight; more decompositions exist.
