Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61556, here are decompositions:
- 3 + 61553 = 61556
- 13 + 61543 = 61556
- 37 + 61519 = 61556
- 73 + 61483 = 61556
- 139 + 61417 = 61556
- 193 + 61363 = 61556
- 199 + 61357 = 61556
- 223 + 61333 = 61556
Showing the first eight; more decompositions exist.
