Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532210, here are decompositions:
- 7 + 31532203 = 31532210
- 43 + 31532167 = 31532210
- 97 + 31532113 = 31532210
- 139 + 31532071 = 31532210
- 397 + 31531813 = 31532210
- 571 + 31531639 = 31532210
- 631 + 31531579 = 31532210
- 727 + 31531483 = 31532210
Showing the first eight; more decompositions exist.
