Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80190, here are decompositions:
- 13 + 80177 = 80190
- 17 + 80173 = 80190
- 23 + 80167 = 80190
- 37 + 80153 = 80190
- 41 + 80149 = 80190
- 43 + 80147 = 80190
- 79 + 80111 = 80190
- 83 + 80107 = 80190
Showing the first eight; more decompositions exist.
