Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61942, here are decompositions:
- 71 + 61871 = 61942
- 191 + 61751 = 61942
- 239 + 61703 = 61942
- 269 + 61673 = 61942
- 311 + 61631 = 61942
- 359 + 61583 = 61942
- 383 + 61559 = 61942
- 389 + 61553 = 61942
Showing the first eight; more decompositions exist.
