Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61842, here are decompositions:
- 5 + 61837 = 61842
- 23 + 61819 = 61842
- 29 + 61813 = 61842
- 61 + 61781 = 61842
- 113 + 61729 = 61842
- 139 + 61703 = 61842
- 191 + 61651 = 61842
- 199 + 61643 = 61842
Showing the first eight; more decompositions exist.
