Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477404, here are decompositions:
- 5 + 31477399 = 31477404
- 53 + 31477351 = 31477404
- 83 + 31477321 = 31477404
- 103 + 31477301 = 31477404
- 113 + 31477291 = 31477404
- 191 + 31477213 = 31477404
- 197 + 31477207 = 31477404
- 223 + 31477181 = 31477404
Showing the first eight; more decompositions exist.
