Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42212, here are decompositions:
- 3 + 42209 = 42212
- 19 + 42193 = 42212
- 31 + 42181 = 42212
- 43 + 42169 = 42212
- 73 + 42139 = 42212
- 139 + 42073 = 42212
- 151 + 42061 = 42212
- 193 + 42019 = 42212
Showing the first eight; more decompositions exist.
