Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147482718, here are decompositions:
- 37 + 2147482681 = 2147482718
- 97 + 2147482621 = 2147482718
- 127 + 2147482591 = 2147482718
- 211 + 2147482507 = 2147482718
- 487 + 2147482231 = 2147482718
- 751 + 2147481967 = 2147482718
- 769 + 2147481949 = 2147482718
- 811 + 2147481907 = 2147482718
Showing the first eight; more decompositions exist.
