Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528468, here are decompositions:
- 17 + 31528451 = 31528468
- 131 + 31528337 = 31528468
- 227 + 31528241 = 31528468
- 239 + 31528229 = 31528468
- 311 + 31528157 = 31528468
- 317 + 31528151 = 31528468
- 347 + 31528121 = 31528468
- 401 + 31528067 = 31528468
Showing the first eight; more decompositions exist.
