Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543476, here are decompositions:
- 23 + 31543453 = 31543476
- 47 + 31543429 = 31543476
- 79 + 31543397 = 31543476
- 127 + 31543349 = 31543476
- 233 + 31543243 = 31543476
- 257 + 31543219 = 31543476
- 269 + 31543207 = 31543476
- 313 + 31543163 = 31543476
Showing the first eight; more decompositions exist.
