Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42192, here are decompositions:
- 5 + 42187 = 42192
- 11 + 42181 = 42192
- 13 + 42179 = 42192
- 23 + 42169 = 42192
- 53 + 42139 = 42192
- 61 + 42131 = 42192
- 103 + 42089 = 42192
- 109 + 42083 = 42192
Showing the first eight; more decompositions exist.
