Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42190, here are decompositions:
- 3 + 42187 = 42190
- 11 + 42179 = 42190
- 59 + 42131 = 42190
- 89 + 42101 = 42190
- 101 + 42089 = 42190
- 107 + 42083 = 42190
- 167 + 42023 = 42190
- 173 + 42017 = 42190
Showing the first eight; more decompositions exist.
