Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42454, here are decompositions:
- 3 + 42451 = 42454
- 11 + 42443 = 42454
- 17 + 42437 = 42454
- 47 + 42407 = 42454
- 131 + 42323 = 42454
- 173 + 42281 = 42454
- 197 + 42257 = 42454
- 227 + 42227 = 42454
Showing the first eight; more decompositions exist.
