Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547224, here are decompositions:
- 47 + 31547177 = 31547224
- 131 + 31547093 = 31547224
- 227 + 31546997 = 31547224
- 311 + 31546913 = 31547224
- 503 + 31546721 = 31547224
- 563 + 31546661 = 31547224
- 587 + 31546637 = 31547224
- 641 + 31546583 = 31547224
Showing the first eight; more decompositions exist.
