Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20308, here are decompositions:
- 11 + 20297 = 20308
- 47 + 20261 = 20308
- 59 + 20249 = 20308
- 89 + 20219 = 20308
- 107 + 20201 = 20308
- 131 + 20177 = 20308
- 179 + 20129 = 20308
- 191 + 20117 = 20308
Showing the first eight; more decompositions exist.
