Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 61918, here are decompositions:
- 47 + 61871 = 61918
- 137 + 61781 = 61918
- 167 + 61751 = 61918
- 251 + 61667 = 61918
- 281 + 61637 = 61918
- 359 + 61559 = 61918
- 431 + 61487 = 61918
- 449 + 61469 = 61918
Showing the first eight; more decompositions exist.
