Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61770, here are decompositions:
- 13 + 61757 = 61770
- 19 + 61751 = 61770
- 41 + 61729 = 61770
- 47 + 61723 = 61770
- 53 + 61717 = 61770
- 67 + 61703 = 61770
- 83 + 61687 = 61770
- 89 + 61681 = 61770
Showing the first eight; more decompositions exist.
