Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543494, here are decompositions:
- 5 + 31543489 = 31543494
- 13 + 31543481 = 31543494
- 41 + 31543453 = 31543494
- 43 + 31543451 = 31543494
- 97 + 31543397 = 31543494
- 163 + 31543331 = 31543494
- 193 + 31543301 = 31543494
- 251 + 31543243 = 31543494
Showing the first eight; more decompositions exist.
