Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22218, here are decompositions:
- 29 + 22189 = 22218
- 47 + 22171 = 22218
- 59 + 22159 = 22218
- 61 + 22157 = 22218
- 71 + 22147 = 22218
- 89 + 22129 = 22218
- 107 + 22111 = 22218
- 109 + 22109 = 22218
Showing the first eight; more decompositions exist.
