Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529050, here are decompositions:
- 53 + 31528997 = 31529050
- 83 + 31528967 = 31529050
- 197 + 31528853 = 31529050
- 227 + 31528823 = 31529050
- 239 + 31528811 = 31529050
- 353 + 31528697 = 31529050
- 491 + 31528559 = 31529050
- 503 + 31528547 = 31529050
Showing the first eight; more decompositions exist.
