Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11564, here are decompositions:
- 13 + 11551 = 11564
- 37 + 11527 = 11564
- 61 + 11503 = 11564
- 67 + 11497 = 11564
- 73 + 11491 = 11564
- 97 + 11467 = 11564
- 127 + 11437 = 11564
- 181 + 11383 = 11564
Showing the first eight; more decompositions exist.
