Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55566, here are decompositions:
- 19 + 55547 = 55566
- 37 + 55529 = 55566
- 79 + 55487 = 55566
- 97 + 55469 = 55566
- 109 + 55457 = 55566
- 127 + 55439 = 55566
- 167 + 55399 = 55566
- 193 + 55373 = 55566
Showing the first eight; more decompositions exist.
