Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534072, here are decompositions:
- 5 + 31534067 = 31534072
- 113 + 31533959 = 31534072
- 149 + 31533923 = 31534072
- 233 + 31533839 = 31534072
- 239 + 31533833 = 31534072
- 281 + 31533791 = 31534072
- 431 + 31533641 = 31534072
- 461 + 31533611 = 31534072
Showing the first eight; more decompositions exist.
