Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31466028, here are decompositions:
- 29 + 31465999 = 31466028
- 137 + 31465891 = 31466028
- 149 + 31465879 = 31466028
- 179 + 31465849 = 31466028
- 197 + 31465831 = 31466028
- 199 + 31465829 = 31466028
- 227 + 31465801 = 31466028
- 239 + 31465789 = 31466028
Showing the first eight; more decompositions exist.
