Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31478134, here are decompositions:
- 5 + 31478129 = 31478134
- 53 + 31478081 = 31478134
- 167 + 31477967 = 31478134
- 197 + 31477937 = 31478134
- 227 + 31477907 = 31478134
- 251 + 31477883 = 31478134
- 257 + 31477877 = 31478134
- 263 + 31477871 = 31478134
Showing the first eight; more decompositions exist.
