Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 55830, here are decompositions:
- 7 + 55823 = 55830
- 11 + 55819 = 55830
- 13 + 55817 = 55830
- 17 + 55813 = 55830
- 23 + 55807 = 55830
- 31 + 55799 = 55830
- 37 + 55793 = 55830
- 43 + 55787 = 55830
Showing the first eight; more decompositions exist.
