Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147482648, here are decompositions:
- 71 + 2147482577 = 2147482648
- 167 + 2147482481 = 2147482648
- 239 + 2147482409 = 2147482648
- 281 + 2147482367 = 2147482648
- 557 + 2147482091 = 2147482648
- 821 + 2147481827 = 2147482648
- 1019 + 2147481629 = 2147482648
- 1289 + 2147481359 = 2147482648
Showing the first eight; more decompositions exist.
