Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49978, here are decompositions:
- 41 + 49937 = 49978
- 59 + 49919 = 49978
- 101 + 49877 = 49978
- 107 + 49871 = 49978
- 167 + 49811 = 49978
- 191 + 49787 = 49978
- 239 + 49739 = 49978
- 251 + 49727 = 49978
Showing the first eight; more decompositions exist.
