Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61894, here are decompositions:
- 23 + 61871 = 61894
- 113 + 61781 = 61894
- 137 + 61757 = 61894
- 191 + 61703 = 61894
- 227 + 61667 = 61894
- 251 + 61643 = 61894
- 257 + 61637 = 61894
- 263 + 61631 = 61894
Showing the first eight; more decompositions exist.
