Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115978, here are decompositions:
- 47 + 115931 = 115978
- 101 + 115877 = 115978
- 167 + 115811 = 115978
- 197 + 115781 = 115978
- 227 + 115751 = 115978
- 251 + 115727 = 115978
- 347 + 115631 = 115978
- 389 + 115589 = 115978
Showing the first eight; more decompositions exist.
