Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22220, here are decompositions:
- 31 + 22189 = 22220
- 61 + 22159 = 22220
- 67 + 22153 = 22220
- 73 + 22147 = 22220
- 97 + 22123 = 22220
- 109 + 22111 = 22220
- 127 + 22093 = 22220
- 157 + 22063 = 22220
Showing the first eight; more decompositions exist.
