Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453246, here are decompositions:
- 5 + 31453241 = 31453246
- 53 + 31453193 = 31453246
- 89 + 31453157 = 31453246
- 113 + 31453133 = 31453246
- 269 + 31452977 = 31453246
- 443 + 31452803 = 31453246
- 563 + 31452683 = 31453246
- 569 + 31452677 = 31453246
Showing the first eight; more decompositions exist.
