Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61906, here are decompositions:
- 149 + 61757 = 61906
- 233 + 61673 = 61906
- 239 + 61667 = 61906
- 263 + 61643 = 61906
- 269 + 61637 = 61906
- 293 + 61613 = 61906
- 347 + 61559 = 61906
- 353 + 61553 = 61906
Showing the first eight; more decompositions exist.
