Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 44640, here are decompositions:
- 7 + 44633 = 44640
- 17 + 44623 = 44640
- 19 + 44621 = 44640
- 23 + 44617 = 44640
- 53 + 44587 = 44640
- 61 + 44579 = 44640
- 97 + 44543 = 44640
- 103 + 44537 = 44640
Showing the first eight; more decompositions exist.
