Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564814, here are decompositions:
- 7 + 31564807 = 31564814
- 157 + 31564657 = 31564814
- 223 + 31564591 = 31564814
- 283 + 31564531 = 31564814
- 313 + 31564501 = 31564814
- 367 + 31564447 = 31564814
- 487 + 31564327 = 31564814
- 571 + 31564243 = 31564814
Showing the first eight; more decompositions exist.
