Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541982, here are decompositions:
- 5 + 31541977 = 31541982
- 11 + 31541971 = 31541982
- 79 + 31541903 = 31541982
- 83 + 31541899 = 31541982
- 89 + 31541893 = 31541982
- 113 + 31541869 = 31541982
- 331 + 31541651 = 31541982
- 349 + 31541633 = 31541982
Showing the first eight; more decompositions exist.
