Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61660, here are decompositions:
- 3 + 61657 = 61660
- 17 + 61643 = 61660
- 23 + 61637 = 61660
- 29 + 61631 = 61660
- 47 + 61613 = 61660
- 101 + 61559 = 61660
- 107 + 61553 = 61660
- 113 + 61547 = 61660
Showing the first eight; more decompositions exist.
