Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 97880, here are decompositions:
- 19 + 97861 = 97880
- 31 + 97849 = 97880
- 37 + 97843 = 97880
- 67 + 97813 = 97880
- 103 + 97777 = 97880
- 109 + 97771 = 97880
- 151 + 97729 = 97880
- 193 + 97687 = 97880
Showing the first eight; more decompositions exist.
