Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147482688, here are decompositions:
- 7 + 2147482681 = 2147482688
- 67 + 2147482621 = 2147482688
- 97 + 2147482591 = 2147482688
- 181 + 2147482507 = 2147482688
- 271 + 2147482417 = 2147482688
- 397 + 2147482291 = 2147482688
- 457 + 2147482231 = 2147482688
- 607 + 2147482081 = 2147482688
Showing the first eight; more decompositions exist.
