Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49900, here are decompositions:
- 23 + 49877 = 49900
- 29 + 49871 = 49900
- 47 + 49853 = 49900
- 89 + 49811 = 49900
- 113 + 49787 = 49900
- 173 + 49727 = 49900
- 233 + 49667 = 49900
- 353 + 49547 = 49900
Showing the first eight; more decompositions exist.
