Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42112, here are decompositions:
- 11 + 42101 = 42112
- 23 + 42089 = 42112
- 29 + 42083 = 42112
- 41 + 42071 = 42112
- 89 + 42023 = 42112
- 113 + 41999 = 42112
- 131 + 41981 = 42112
- 233 + 41879 = 42112
Showing the first eight; more decompositions exist.
