Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42382, here are decompositions:
- 3 + 42379 = 42382
- 23 + 42359 = 42382
- 59 + 42323 = 42382
- 83 + 42299 = 42382
- 89 + 42293 = 42382
- 101 + 42281 = 42382
- 173 + 42209 = 42382
- 251 + 42131 = 42382
Showing the first eight; more decompositions exist.
