Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11640, here are decompositions:
- 7 + 11633 = 11640
- 19 + 11621 = 11640
- 23 + 11617 = 11640
- 43 + 11597 = 11640
- 47 + 11593 = 11640
- 53 + 11587 = 11640
- 61 + 11579 = 11640
- 89 + 11551 = 11640
Showing the first eight; more decompositions exist.
