Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20226, here are decompositions:
- 7 + 20219 = 20226
- 43 + 20183 = 20226
- 53 + 20173 = 20226
- 79 + 20147 = 20226
- 83 + 20143 = 20226
- 97 + 20129 = 20226
- 103 + 20123 = 20226
- 109 + 20117 = 20226
Showing the first eight; more decompositions exist.
