Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147474722, here are decompositions:
- 5 + 2147474717 = 2147474722
- 11 + 2147474711 = 2147474722
- 191 + 2147474531 = 2147474722
- 443 + 2147474279 = 2147474722
- 509 + 2147474213 = 2147474722
- 521 + 2147474201 = 2147474722
- 563 + 2147474159 = 2147474722
- 599 + 2147474123 = 2147474722
Showing the first eight; more decompositions exist.
