Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55744, here are decompositions:
- 11 + 55733 = 55744
- 23 + 55721 = 55744
- 47 + 55697 = 55744
- 53 + 55691 = 55744
- 71 + 55673 = 55744
- 83 + 55661 = 55744
- 113 + 55631 = 55744
- 197 + 55547 = 55744
Showing the first eight; more decompositions exist.
