Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55664, here are decompositions:
- 3 + 55661 = 55664
- 31 + 55633 = 55664
- 43 + 55621 = 55664
- 61 + 55603 = 55664
- 163 + 55501 = 55664
- 223 + 55441 = 55664
- 283 + 55381 = 55664
- 313 + 55351 = 55664
Showing the first eight; more decompositions exist.
