Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61800, here are decompositions:
- 19 + 61781 = 61800
- 43 + 61757 = 61800
- 71 + 61729 = 61800
- 83 + 61717 = 61800
- 97 + 61703 = 61800
- 113 + 61687 = 61800
- 127 + 61673 = 61800
- 149 + 61651 = 61800
Showing the first eight; more decompositions exist.
