Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462090, here are decompositions:
- 83 + 31462007 = 31462090
- 113 + 31461977 = 31462090
- 167 + 31461923 = 31462090
- 197 + 31461893 = 31462090
- 239 + 31461851 = 31462090
- 311 + 31461779 = 31462090
- 347 + 31461743 = 31462090
- 353 + 31461737 = 31462090
Showing the first eight; more decompositions exist.
