Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18846, here are decompositions:
- 7 + 18839 = 18846
- 43 + 18803 = 18846
- 53 + 18793 = 18846
- 59 + 18787 = 18846
- 73 + 18773 = 18846
- 89 + 18757 = 18846
- 97 + 18749 = 18846
- 103 + 18743 = 18846
Showing the first eight; more decompositions exist.
