Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42130, here are decompositions:
- 29 + 42101 = 42130
- 41 + 42089 = 42130
- 47 + 42083 = 42130
- 59 + 42071 = 42130
- 107 + 42023 = 42130
- 113 + 42017 = 42130
- 131 + 41999 = 42130
- 149 + 41981 = 42130
Showing the first eight; more decompositions exist.
