Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 97428, here are decompositions:
- 5 + 97423 = 97428
- 31 + 97397 = 97428
- 41 + 97387 = 97428
- 47 + 97381 = 97428
- 59 + 97369 = 97428
- 61 + 97367 = 97428
- 101 + 97327 = 97428
- 127 + 97301 = 97428
Showing the first eight; more decompositions exist.
