Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 97440, here are decompositions:
- 11 + 97429 = 97440
- 17 + 97423 = 97440
- 43 + 97397 = 97440
- 53 + 97387 = 97440
- 59 + 97381 = 97440
- 61 + 97379 = 97440
- 67 + 97373 = 97440
- 71 + 97369 = 97440
Showing the first eight; more decompositions exist.
