Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8380, here are decompositions:
- 3 + 8377 = 8380
- 11 + 8369 = 8380
- 17 + 8363 = 8380
- 83 + 8297 = 8380
- 89 + 8291 = 8380
- 107 + 8273 = 8380
- 137 + 8243 = 8380
- 149 + 8231 = 8380
Showing the first eight; more decompositions exist.
