Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20222, here are decompositions:
- 3 + 20219 = 20222
- 61 + 20161 = 20222
- 73 + 20149 = 20222
- 79 + 20143 = 20222
- 109 + 20113 = 20222
- 151 + 20071 = 20222
- 193 + 20029 = 20222
- 199 + 20023 = 20222
Showing the first eight; more decompositions exist.
