Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61912, here are decompositions:
- 3 + 61909 = 61912
- 41 + 61871 = 61912
- 131 + 61781 = 61912
- 239 + 61673 = 61912
- 269 + 61643 = 61912
- 281 + 61631 = 61912
- 353 + 61559 = 61912
- 359 + 61553 = 61912
Showing the first eight; more decompositions exist.
