Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42386, here are decompositions:
- 7 + 42379 = 42386
- 13 + 42373 = 42386
- 37 + 42349 = 42386
- 79 + 42307 = 42386
- 103 + 42283 = 42386
- 163 + 42223 = 42386
- 193 + 42193 = 42386
- 199 + 42187 = 42386
Showing the first eight; more decompositions exist.
