Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 98640, here are decompositions:
- 13 + 98627 = 98640
- 19 + 98621 = 98640
- 43 + 98597 = 98640
- 67 + 98573 = 98640
- 79 + 98561 = 98640
- 97 + 98543 = 98640
- 107 + 98533 = 98640
- 149 + 98491 = 98640
Showing the first eight; more decompositions exist.
