Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55872, here are decompositions:
- 23 + 55849 = 55872
- 29 + 55843 = 55872
- 43 + 55829 = 55872
- 53 + 55819 = 55872
- 59 + 55813 = 55872
- 73 + 55799 = 55872
- 79 + 55793 = 55872
- 109 + 55763 = 55872
Showing the first eight; more decompositions exist.
