Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49780, here are decompositions:
- 23 + 49757 = 49780
- 41 + 49739 = 49780
- 53 + 49727 = 49780
- 83 + 49697 = 49780
- 113 + 49667 = 49780
- 167 + 49613 = 49780
- 233 + 49547 = 49780
- 251 + 49529 = 49780
Showing the first eight; more decompositions exist.
