Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61868, here are decompositions:
- 7 + 61861 = 61868
- 31 + 61837 = 61868
- 139 + 61729 = 61868
- 151 + 61717 = 61868
- 181 + 61687 = 61868
- 211 + 61657 = 61868
- 241 + 61627 = 61868
- 307 + 61561 = 61868
Showing the first eight; more decompositions exist.
