Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86278, here are decompositions:
- 29 + 86249 = 86278
- 107 + 86171 = 86278
- 167 + 86111 = 86278
- 251 + 86027 = 86278
- 347 + 85931 = 86278
- 389 + 85889 = 86278
- 431 + 85847 = 86278
- 449 + 85829 = 86278
Showing the first eight; more decompositions exist.
