Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543300, here are decompositions:
- 83 + 31543217 = 31543300
- 137 + 31543163 = 31543300
- 167 + 31543133 = 31543300
- 197 + 31543103 = 31543300
- 233 + 31543067 = 31543300
- 281 + 31543019 = 31543300
- 359 + 31542941 = 31543300
- 389 + 31542911 = 31543300
Showing the first eight; more decompositions exist.
