Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 112840, here are decompositions:
- 41 + 112799 = 112840
- 53 + 112787 = 112840
- 83 + 112757 = 112840
- 149 + 112691 = 112840
- 197 + 112643 = 112840
- 239 + 112601 = 112840
- 251 + 112589 = 112840
- 257 + 112583 = 112840
Showing the first eight; more decompositions exist.
