Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42286, here are decompositions:
- 3 + 42283 = 42286
- 5 + 42281 = 42286
- 29 + 42257 = 42286
- 47 + 42239 = 42286
- 59 + 42227 = 42286
- 89 + 42197 = 42286
- 107 + 42179 = 42286
- 197 + 42089 = 42286
Showing the first eight; more decompositions exist.
