Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61740, here are decompositions:
- 11 + 61729 = 61740
- 17 + 61723 = 61740
- 23 + 61717 = 61740
- 37 + 61703 = 61740
- 53 + 61687 = 61740
- 59 + 61681 = 61740
- 67 + 61673 = 61740
- 73 + 61667 = 61740
Showing the first eight; more decompositions exist.
