Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15648, here are decompositions:
- 5 + 15643 = 15648
- 7 + 15641 = 15648
- 19 + 15629 = 15648
- 29 + 15619 = 15648
- 41 + 15607 = 15648
- 47 + 15601 = 15648
- 67 + 15581 = 15648
- 79 + 15569 = 15648
Showing the first eight; more decompositions exist.
