Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55890, here are decompositions:
- 19 + 55871 = 55890
- 41 + 55849 = 55890
- 47 + 55843 = 55890
- 53 + 55837 = 55890
- 61 + 55829 = 55890
- 67 + 55823 = 55890
- 71 + 55819 = 55890
- 73 + 55817 = 55890
Showing the first eight; more decompositions exist.
