Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23872, here are decompositions:
- 3 + 23869 = 23872
- 41 + 23831 = 23872
- 53 + 23819 = 23872
- 59 + 23813 = 23872
- 71 + 23801 = 23872
- 83 + 23789 = 23872
- 131 + 23741 = 23872
- 239 + 23633 = 23872
Showing the first eight; more decompositions exist.
