Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543434, here are decompositions:
- 5 + 31543429 = 31543434
- 37 + 31543397 = 31543434
- 73 + 31543361 = 31543434
- 103 + 31543331 = 31543434
- 191 + 31543243 = 31543434
- 211 + 31543223 = 31543434
- 227 + 31543207 = 31543434
- 271 + 31543163 = 31543434
Showing the first eight; more decompositions exist.
