Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28262, here are decompositions:
- 43 + 28219 = 28262
- 61 + 28201 = 28262
- 79 + 28183 = 28262
- 139 + 28123 = 28262
- 151 + 28111 = 28262
- 163 + 28099 = 28262
- 181 + 28081 = 28262
- 193 + 28069 = 28262
Showing the first eight; more decompositions exist.
