Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543932, here are decompositions:
- 5 + 31543927 = 31543932
- 19 + 31543913 = 31543932
- 29 + 31543903 = 31543932
- 59 + 31543873 = 31543932
- 61 + 31543871 = 31543932
- 73 + 31543859 = 31543932
- 89 + 31543843 = 31543932
- 103 + 31543829 = 31543932
Showing the first eight; more decompositions exist.
