Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11506, here are decompositions:
- 3 + 11503 = 11506
- 17 + 11489 = 11506
- 23 + 11483 = 11506
- 59 + 11447 = 11506
- 83 + 11423 = 11506
- 107 + 11399 = 11506
- 113 + 11393 = 11506
- 137 + 11369 = 11506
Showing the first eight; more decompositions exist.
