Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22280, here are decompositions:
- 3 + 22277 = 22280
- 7 + 22273 = 22280
- 109 + 22171 = 22280
- 127 + 22153 = 22280
- 151 + 22129 = 22280
- 157 + 22123 = 22280
- 229 + 22051 = 22280
- 241 + 22039 = 22280
Showing the first eight; more decompositions exist.
