Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19946, here are decompositions:
- 19 + 19927 = 19946
- 79 + 19867 = 19946
- 103 + 19843 = 19946
- 127 + 19819 = 19946
- 193 + 19753 = 19946
- 229 + 19717 = 19946
- 337 + 19609 = 19946
- 349 + 19597 = 19946
Showing the first eight; more decompositions exist.
