Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2390, here are decompositions:
- 7 + 2383 = 2390
- 13 + 2377 = 2390
- 19 + 2371 = 2390
- 43 + 2347 = 2390
- 79 + 2311 = 2390
- 97 + 2293 = 2390
- 103 + 2287 = 2390
- 109 + 2281 = 2390
Showing the first eight; more decompositions exist.
