Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587840, here are decompositions:
- 7 + 33587833 = 33587840
- 31 + 33587809 = 33587840
- 37 + 33587803 = 33587840
- 79 + 33587761 = 33587840
- 103 + 33587737 = 33587840
- 109 + 33587731 = 33587840
- 157 + 33587683 = 33587840
- 163 + 33587677 = 33587840
Showing the first eight; more decompositions exist.
