Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 97400, here are decompositions:
- 3 + 97397 = 97400
- 13 + 97387 = 97400
- 19 + 97381 = 97400
- 31 + 97369 = 97400
- 73 + 97327 = 97400
- 97 + 97303 = 97400
- 223 + 97177 = 97400
- 229 + 97171 = 97400
Showing the first eight; more decompositions exist.
