Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42182, here are decompositions:
- 3 + 42179 = 42182
- 13 + 42169 = 42182
- 43 + 42139 = 42182
- 109 + 42073 = 42182
- 139 + 42043 = 42182
- 163 + 42019 = 42182
- 199 + 41983 = 42182
- 223 + 41959 = 42182
Showing the first eight; more decompositions exist.
