Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5544, here are decompositions:
- 13 + 5531 = 5544
- 17 + 5527 = 5544
- 23 + 5521 = 5544
- 37 + 5507 = 5544
- 41 + 5503 = 5544
- 43 + 5501 = 5544
- 61 + 5483 = 5544
- 67 + 5477 = 5544
Showing the first eight; more decompositions exist.
