Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528948, here are decompositions:
- 107 + 31528841 = 31528948
- 137 + 31528811 = 31528948
- 197 + 31528751 = 31528948
- 251 + 31528697 = 31528948
- 389 + 31528559 = 31528948
- 401 + 31528547 = 31528948
- 449 + 31528499 = 31528948
- 599 + 31528349 = 31528948
Showing the first eight; more decompositions exist.
