Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543350, here are decompositions:
- 19 + 31543331 = 31543350
- 107 + 31543243 = 31543350
- 127 + 31543223 = 31543350
- 131 + 31543219 = 31543350
- 271 + 31543079 = 31543350
- 281 + 31543069 = 31543350
- 283 + 31543067 = 31543350
- 331 + 31543019 = 31543350
Showing the first eight; more decompositions exist.
