Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541022, here are decompositions:
- 5 + 31541017 = 31541022
- 31 + 31540991 = 31541022
- 43 + 31540979 = 31541022
- 61 + 31540961 = 31541022
- 83 + 31540939 = 31541022
- 101 + 31540921 = 31541022
- 151 + 31540871 = 31541022
- 199 + 31540823 = 31541022
Showing the first eight; more decompositions exist.
