Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42148, here are decompositions:
- 17 + 42131 = 42148
- 47 + 42101 = 42148
- 59 + 42089 = 42148
- 131 + 42017 = 42148
- 149 + 41999 = 42148
- 167 + 41981 = 42148
- 179 + 41969 = 42148
- 191 + 41957 = 42148
Showing the first eight; more decompositions exist.
