Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 91902, here are decompositions:
- 29 + 91873 = 91902
- 61 + 91841 = 91902
- 79 + 91823 = 91902
- 89 + 91813 = 91902
- 101 + 91801 = 91902
- 131 + 91771 = 91902
- 149 + 91753 = 91902
- 191 + 91711 = 91902
Showing the first eight; more decompositions exist.
