Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2492, here are decompositions:
- 19 + 2473 = 2492
- 103 + 2389 = 2492
- 109 + 2383 = 2492
- 151 + 2341 = 2492
- 181 + 2311 = 2492
- 199 + 2293 = 2492
- 211 + 2281 = 2492
- 223 + 2269 = 2492
Showing the first eight; more decompositions exist.
