Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61600, here are decompositions:
- 17 + 61583 = 61600
- 41 + 61559 = 61600
- 47 + 61553 = 61600
- 53 + 61547 = 61600
- 89 + 61511 = 61600
- 107 + 61493 = 61600
- 113 + 61487 = 61600
- 131 + 61469 = 61600
Showing the first eight; more decompositions exist.
