Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91506, here are decompositions:
- 7 + 91499 = 91506
- 13 + 91493 = 91506
- 43 + 91463 = 91506
- 47 + 91459 = 91506
- 53 + 91453 = 91506
- 73 + 91433 = 91506
- 83 + 91423 = 91506
- 109 + 91397 = 91506
Showing the first eight; more decompositions exist.
