Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2442, here are decompositions:
- 5 + 2437 = 2442
- 19 + 2423 = 2442
- 31 + 2411 = 2442
- 43 + 2399 = 2442
- 53 + 2389 = 2442
- 59 + 2383 = 2442
- 61 + 2381 = 2442
- 71 + 2371 = 2442
Showing the first eight; more decompositions exist.
