Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 492878, here are decompositions:
- 7 + 492871 = 492878
- 79 + 492799 = 492878
- 97 + 492781 = 492878
- 109 + 492769 = 492878
- 157 + 492721 = 492878
- 277 + 492601 = 492878
- 367 + 492511 = 492878
- 457 + 492421 = 492878
Showing the first eight; more decompositions exist.
