Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 83980, here are decompositions:
- 11 + 83969 = 83980
- 41 + 83939 = 83980
- 47 + 83933 = 83980
- 59 + 83921 = 83980
- 89 + 83891 = 83980
- 107 + 83873 = 83980
- 137 + 83843 = 83980
- 167 + 83813 = 83980
Showing the first eight; more decompositions exist.
