Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73870, here are decompositions:
- 3 + 73867 = 73870
- 11 + 73859 = 73870
- 23 + 73847 = 73870
- 47 + 73823 = 73870
- 113 + 73757 = 73870
- 149 + 73721 = 73870
- 191 + 73679 = 73870
- 197 + 73673 = 73870
Showing the first eight; more decompositions exist.
