Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 97720, here are decompositions:
- 47 + 97673 = 97720
- 71 + 97649 = 97720
- 107 + 97613 = 97720
- 113 + 97607 = 97720
- 137 + 97583 = 97720
- 149 + 97571 = 97720
- 167 + 97553 = 97720
- 173 + 97547 = 97720
Showing the first eight; more decompositions exist.
