Also seen as
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11658, here are decompositions:
- 37 + 11621 = 11658
- 41 + 11617 = 11658
- 61 + 11597 = 11658
- 71 + 11587 = 11658
- 79 + 11579 = 11658
- 107 + 11551 = 11658
- 109 + 11549 = 11658
- 131 + 11527 = 11658
Showing the first eight; more decompositions exist.
