Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 97872, here are decompositions:
- 11 + 97861 = 97872
- 13 + 97859 = 97872
- 23 + 97849 = 97872
- 29 + 97843 = 97872
- 31 + 97841 = 97872
- 43 + 97829 = 97872
- 59 + 97813 = 97872
- 83 + 97789 = 97872
Showing the first eight; more decompositions exist.
