Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532126, here are decompositions:
- 13 + 31532113 = 31532126
- 37 + 31532089 = 31532126
- 313 + 31531813 = 31532126
- 487 + 31531639 = 31532126
- 499 + 31531627 = 31532126
- 547 + 31531579 = 31532126
- 643 + 31531483 = 31532126
- 673 + 31531453 = 31532126
Showing the first eight; more decompositions exist.
