Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22140, here are decompositions:
- 7 + 22133 = 22140
- 11 + 22129 = 22140
- 17 + 22123 = 22140
- 29 + 22111 = 22140
- 31 + 22109 = 22140
- 47 + 22093 = 22140
- 61 + 22079 = 22140
- 67 + 22073 = 22140
Showing the first eight; more decompositions exist.
