Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11620, here are decompositions:
- 3 + 11617 = 11620
- 23 + 11597 = 11620
- 41 + 11579 = 11620
- 71 + 11549 = 11620
- 101 + 11519 = 11620
- 131 + 11489 = 11620
- 137 + 11483 = 11620
- 149 + 11471 = 11620
Showing the first eight; more decompositions exist.
