Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477310, here are decompositions:
- 19 + 31477291 = 31477310
- 97 + 31477213 = 31477310
- 103 + 31477207 = 31477310
- 199 + 31477111 = 31477310
- 211 + 31477099 = 31477310
- 283 + 31477027 = 31477310
- 379 + 31476931 = 31477310
- 439 + 31476871 = 31477310
Showing the first eight; more decompositions exist.
