Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20046, here are decompositions:
- 17 + 20029 = 20046
- 23 + 20023 = 20046
- 53 + 19993 = 20046
- 67 + 19979 = 20046
- 73 + 19973 = 20046
- 83 + 19963 = 20046
- 97 + 19949 = 20046
- 109 + 19937 = 20046
Showing the first eight; more decompositions exist.
