Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61880, here are decompositions:
- 19 + 61861 = 61880
- 37 + 61843 = 61880
- 43 + 61837 = 61880
- 61 + 61819 = 61880
- 67 + 61813 = 61880
- 151 + 61729 = 61880
- 157 + 61723 = 61880
- 163 + 61717 = 61880
Showing the first eight; more decompositions exist.
