Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 97100, here are decompositions:
- 19 + 97081 = 97100
- 61 + 97039 = 97100
- 79 + 97021 = 97100
- 97 + 97003 = 97100
- 103 + 96997 = 97100
- 127 + 96973 = 97100
- 193 + 96907 = 97100
- 277 + 96823 = 97100
Showing the first eight; more decompositions exist.
