Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543396, here are decompositions:
- 47 + 31543349 = 31543396
- 173 + 31543223 = 31543396
- 179 + 31543217 = 31543396
- 233 + 31543163 = 31543396
- 263 + 31543133 = 31543396
- 293 + 31543103 = 31543396
- 317 + 31543079 = 31543396
- 569 + 31542827 = 31543396
Showing the first eight; more decompositions exist.
