Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2486, here are decompositions:
- 13 + 2473 = 2486
- 19 + 2467 = 2486
- 97 + 2389 = 2486
- 103 + 2383 = 2486
- 109 + 2377 = 2486
- 139 + 2347 = 2486
- 193 + 2293 = 2486
- 199 + 2287 = 2486
Showing the first eight; more decompositions exist.
