Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83880, here are decompositions:
- 7 + 83873 = 83880
- 11 + 83869 = 83880
- 23 + 83857 = 83880
- 37 + 83843 = 83880
- 47 + 83833 = 83880
- 67 + 83813 = 83880
- 89 + 83791 = 83880
- 103 + 83777 = 83880
Showing the first eight; more decompositions exist.
