Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5644, here are decompositions:
- 3 + 5641 = 5644
- 5 + 5639 = 5644
- 53 + 5591 = 5644
- 71 + 5573 = 5644
- 113 + 5531 = 5644
- 137 + 5507 = 5644
- 167 + 5477 = 5644
- 173 + 5471 = 5644
Showing the first eight; more decompositions exist.
