Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147407704, here are decompositions:
- 5 + 2147407699 = 2147407704
- 7 + 2147407697 = 2147407704
- 23 + 2147407681 = 2147407704
- 37 + 2147407667 = 2147407704
- 47 + 2147407657 = 2147407704
- 83 + 2147407621 = 2147407704
- 241 + 2147407463 = 2147407704
- 367 + 2147407337 = 2147407704
Showing the first eight; more decompositions exist.
