Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20140, here are decompositions:
- 11 + 20129 = 20140
- 17 + 20123 = 20140
- 23 + 20117 = 20140
- 89 + 20051 = 20140
- 149 + 19991 = 20140
- 167 + 19973 = 20140
- 179 + 19961 = 20140
- 191 + 19949 = 20140
Showing the first eight; more decompositions exist.
