Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540968, here are decompositions:
- 7 + 31540961 = 31540968
- 29 + 31540939 = 31540968
- 47 + 31540921 = 31540968
- 97 + 31540871 = 31540968
- 101 + 31540867 = 31540968
- 131 + 31540837 = 31540968
- 181 + 31540787 = 31540968
- 241 + 31540727 = 31540968
Showing the first eight; more decompositions exist.
