Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61966, here are decompositions:
- 5 + 61961 = 61966
- 17 + 61949 = 61966
- 263 + 61703 = 61966
- 293 + 61673 = 61966
- 353 + 61613 = 61966
- 383 + 61583 = 61966
- 419 + 61547 = 61966
- 479 + 61487 = 61966
Showing the first eight; more decompositions exist.
