Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61558, here are decompositions:
- 5 + 61553 = 61558
- 11 + 61547 = 61558
- 47 + 61511 = 61558
- 71 + 61487 = 61558
- 89 + 61469 = 61558
- 149 + 61409 = 61558
- 179 + 61379 = 61558
- 227 + 61331 = 61558
Showing the first eight; more decompositions exist.
