Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20126, here are decompositions:
- 3 + 20123 = 20126
- 13 + 20113 = 20126
- 19 + 20107 = 20126
- 37 + 20089 = 20126
- 79 + 20047 = 20126
- 97 + 20029 = 20126
- 103 + 20023 = 20126
- 163 + 19963 = 20126
Showing the first eight; more decompositions exist.
