Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543534, here are decompositions:
- 3 + 31543531 = 31543534
- 5 + 31543529 = 31543534
- 53 + 31543481 = 31543534
- 83 + 31543451 = 31543534
- 137 + 31543397 = 31543534
- 173 + 31543361 = 31543534
- 233 + 31543301 = 31543534
- 311 + 31543223 = 31543534
Showing the first eight; more decompositions exist.
