Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61860, here are decompositions:
- 17 + 61843 = 61860
- 23 + 61837 = 61860
- 41 + 61819 = 61860
- 47 + 61813 = 61860
- 79 + 61781 = 61860
- 103 + 61757 = 61860
- 109 + 61751 = 61860
- 131 + 61729 = 61860
Showing the first eight; more decompositions exist.
