Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5564, here are decompositions:
- 7 + 5557 = 5564
- 37 + 5527 = 5564
- 43 + 5521 = 5564
- 61 + 5503 = 5564
- 127 + 5437 = 5564
- 151 + 5413 = 5564
- 157 + 5407 = 5564
- 241 + 5323 = 5564
Showing the first eight; more decompositions exist.
