Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543392, here are decompositions:
- 31 + 31543361 = 31543392
- 43 + 31543349 = 31543392
- 61 + 31543331 = 31543392
- 149 + 31543243 = 31543392
- 173 + 31543219 = 31543392
- 211 + 31543181 = 31543392
- 229 + 31543163 = 31543392
- 313 + 31543079 = 31543392
Showing the first eight; more decompositions exist.
