Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533846, here are decompositions:
- 7 + 31533839 = 31533846
- 13 + 31533833 = 31533846
- 17 + 31533829 = 31533846
- 23 + 31533823 = 31533846
- 73 + 31533773 = 31533846
- 83 + 31533763 = 31533846
- 139 + 31533707 = 31533846
- 233 + 31533613 = 31533846
Showing the first eight; more decompositions exist.
